To a solution of 4-aminoisoxazole (2.00 g, 23.79 mmol; CASNo. 108511-97-3) in THF (50 mL) at 0 0C was added pyridine (1.92 mL, 23.79 mmol,) followed by phenyl chloroformate (3.28 mL, 26.17 mmol,). After stirring at 0 0C for 2.5 h, the reaction was warmed to room temp overnight. The reaction was diluted with ethyl acetate and washed with 2M HCI1 water, saturated sodium bicarbonate, and brine. The organic layer was dried over magnesium sulfate, filtered, concentrated, and purified by flash chromatography40 (dichloromethane/hexane) to give the title compound as a white solid (2.07 g, 10.15 mmol, 50%)., 108511-97-3

The synthetic route of 108511-97-3 has been constantly updated, and we look forward to future research findings.

Compound 4 (11.51 g, 0.022 mol),Isoxazol-4-ylamine (11.85g, 0.022mol) and p-toluenesulfonic acid(~0.40g) of the suspension was placed in a mechanical stirrer,In a round bottom flask with an oil bath and a Dean-Stark condenser,The reaction mixture is heated to reflux (internal temperature 150-155 C,Oil bath temperature 170-180 C) 15-18 hours,The reaction was monitored by TLC at the same time. After completion of the reaction, the reaction mixture was cooled to 80 C, and methanol (27 mL) was slowly added through a dropping funnel.The reaction mixture was slowly cooled to room temperature with stirring.The resulting solid was filtered and washed with methanol (45 mL).And dried at 100-120 C for 2 hours.Obtained as a white solid ((3-((4,6-difluorobenzo[d]thiazol-2-yl)methyl)thio)-1-(isoxazol-4-ylamino)-1-oxyl Propane-2-carboxylic acid (9H-fluoren-9-yl)yl carbamate (Compound 5), 9.26 g,The yield was 71%.

A mixture of 2-[(phenylmethyl)oxy]-5-(4-pyridinyl)benzoic acid (may be prepared as described in Description 79; 100 mg, 0.30 mmol), EDC (172 mg, 0.90 mmol) and HOBT (137 mg, 0.90 mmol) in dimethylformamide (3 ml) was stirred in air at room temperature for 1 h, then 4-isoxazolamine (may be prepared as described in Description 95; 100 mg, 1.189 mmol) was added in one charge. The reaction mixture was stirred at room temperature overnight. The reaction mixture was diluted with water (30 mi). The solid was filtered and dried in vacuo to obtain crude product, which was purified with Prep- HPLC (Waters, X-Bridge, 5Mm;30x100mm; A=0.05%NH3.H2O/water, B:MeCN;v=30ml/min;0-7min, 42%-54%; 7-12min, 95%; t=8.0min.) to yield the title compound as a white solid. 34 mg.’HNMR (400 MHz, DMSO-d6): 10.60 (s, 1 H), 9.27 (s, 1 H), 8.65 (s, 1 H), 8.62 (d, 2H, J=5.6), 8.08 {d, 1 H, J=2.0), 7.98 (dd, 1 H, J=2.0, 8.4), 7.74 (d, 2H, J=5.6), 7.52 (d, 2H, J=7.6), 7.42-7.33 (m, 4H), 5.36 (s, 2H).MS (electrospray); m/z [M+H]+ = 372.1
