57684-71-6,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.57684-71-6,3-(Chloromethyl)isoxazole,as a common compound, the synthetic route is as follows.

To a solution of (S)-2-(3-methyl-2,6-dioxo-2,3-dihydro-1H-purin-7(6H)-yl)-N-(6′- (trifluoromethyl)-[2,3′-bipyridin]-6-yl)propanamide (15 mg, 0.033 mmol) and POTASSIUM CARBONATE(9 mg, 0.065 mmol) in DMF (1 mL) was added 3-(chloromethyl)isoxazole (3.7 mg, 0.049 mmol). The mixture was stirred at rt overnight. The mixture was diluted with EA and washed with water, saturated aqueous NH4Cl solution and brine, dried over Na2SO4, and evaporated. The residue was purified by silica gel column chromatography (0-2% MeOH/DCM) to give the product (S)-2-(1-(isoxazol-3-ylmethyl)-3-methyl-2,6-dioxo-2,3-dihydro-1H-purin- 7(6H)-yl)-N-(6′-(trifluoromethyl)-[2,3′-bipyridin]-6-yl)propanamide (16.5 mg, 92% yield) as a white solid.1H NMR (400 MHz, DMSO-D6) delta 11.20 (s, 1H), 9.43 (s, 1H), 8.78 (s, 1H), 8.68 (d, J = 1.8 Hz, 1H), 8.39 (s, 1H), 7.89-8.05 (m, 4H), 6.45 (s, 1H), 5.82 (m, 1H), 5.09 (s, 2H), 3.47(s, 3H), 1.87 (d, J = 7.3 Hz, 3H). MH+ 541.

2-(3-methyl-2,6-dioxo-2,3-dihydro-1H-purin-7(6H)-yl)-N-(6?-methyl-5?-(trifluoromethyl)-[2,3- bipyridin]-6-yl)acetamide (50 mg, 0.109 mmol) and potassium carbonate (25 mg, 0.327 mmol) were combined in DMF (3 mL) then 3-(chloromethyl)isoxazole (16 mg, 0.120 mmol) was added. The reaction was heated at 55oC for 18 h, cooled to RT then concentrated to a residue which was purified by chromatography eluted with MeOH/DCM (1:99 to 3:97) to give 2-(1-(isoxazol-3- ylmethyl)-3-methyl-2,6-dioxo-2,3-dihydro-1H-purin-7(6H)-yl)-N-(6?-methyl-5?- (trifluoromethyl)-[2,3?-bipyridin]-6-yl)acetamide (29 mg, 49.2% yield) as a white solid.1H NMR (CDCl3) delta: 9.45 (brd s, 1H), 9.14 (s, 1H), 8.48 (s, 1H), 8.23 (s, 1H), 8.07 (brd s, 1H), 7.82-7.73 (m, 2H), 7.53 (d, J = 8 Hz, 1H), 6.40 (s, 1H), 5.35 (s, 2H), 5.17 (s, 2H) 3.61 (s, 3H), 2.77 (s, 3H). LCMS: MH+ 541 and TR = 3.005 min.

The synthetic route of 57684-71-6 has been constantly updated, and we look forward to future research findings.

Intermediate 11, tert-butyl 4-(cyclopropylamino)piperid me-i -carboxylate (200 mg, 0.83 mmol) was dissolved in ethanol (10 mL) and sodium bicarbonate (200 mg, 2.38 mmol) was added. The reaction mixture was stirred at 0 C for 30 mm, then Intermediate 14, 3-(chloromethyl)-1 2- oxazole (97 mg, 0.83 mmol) was added dropwise at it The resulting reaction mixture wasstirred at 60 C for 16 h. The solvents were removed in vacuo and the residue was partitioned between H20 (120 mL) and EtOAc (100 mL). The aqueous layer was further extracted with EtOAc (2 x 100 mL) and the combined organic layers were dried (Na2SO4), and the solvents were removed in vacuo. The residue was purified by column chromatography (normal basic activated alumina, 0.5 % to 1 .0 % MeOH in DCM) to give tert-butyl 4-[cyclopropyl(1 ,2-oxazol-3-ylmethyl)amino]piperidine-1-carboxylate (150 mg, 58 %) as a liquid. LCMS (Method I): mlz 322 [M+H] (ES), at 4.92 mi UV active

As the paragraph descriping shows that 57684-71-6 is playing an increasingly important role.
