54593-26-9,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.54593-26-9,3,5-Dimethyl-4-isoxazolecarbaldehyde,as a common compound, the synthetic route is as follows.

[000298] 4-Piperidinone (0.92 gr, 6 mmol) was placed in a 25 ml round bottom flask and cooled to 0 C. Boron trifluoride (10 mL) was added dropwise followed by the aldehyde (1.5 gr, 12 mmol) in one portion. The reaction mixture was stirred overnight at room temperature under nitrogen atmosphere. The reaction was carefully quenched with a saturated solution of NaHCC . The solid precipitated out from the solution was filtered under reduced pressure, washed with water and EtOH to give the intermediate El-1 (Scheme 7) as a yellow solid (1.2 gr, 3.8 mmol, 63%).

As the paragraph descriping shows that 54593-26-9 is playing an increasingly important role.

The mixture was stirred at 0 C for 30 mm. Then 3,Sdimethylisoxazole4-carbaldehyde (1.5 g, 12 mmol) was added to the mixture. The resulting mixture was stirred for 2 h. Saturated aq. NHCi (10 mL) was added to the mixture and the mixture was extracted with EtOAc (3 x 50 mL). The combined organic layers were washed with brine (3 x 15 mL) and dried over Na2504. The solvent was evaporated to aresidue which was purified by silica gel column chromatography (30% EtOAc/petroleum ether) to afford the title compound (900 mg, yield 38%) as a yellow oil. LCMS-P1: 316 [M+H] R = i.48i mm.

Example 1: (2,4-Dichloro-3-phenylquinolin-6-yl)(3,5-dimethylisoxazol-4-yl)methanolTHF (5 mL) was added to a mixture of 6-bromo-2,4-dichloro-3-phenylquinoline (363 mg, 1.03 mmol, Intermediate 1 : step c) and 3,5-dimefhyiisoxazole-4-carbaldehyde (1 80 mg, 1.44 mmol) under a nitrogen atmosphere. The resulting colorless solution was cooled in a dry ice/acetone bath. n-BuLi (1.6 M in hexane, 0.77 mL, 1.23 mmol) was added dropwise and the mixture was stirred at -78 C for 30 minutes, then moved to an ice bath and stirred for 30 minutes. The reaction was quenched by addition of saturated aqueous NH4Cl and was diluted with water. The mixture was extracted three times with EtOAc. The organic phase was dried (Na2SO4), filtered, and concentrated to afford the crude title compound, 1H NMR (400 MHz, DMSO-d6) delta ppm 8.35 (s, 1H), 8.04 (d, J = 8.80 Hz, 1H), 7,74 (dd, J = 1.71 , 8.80 Hz, 1H), 7,48 – 7.62 (m, 3H), 7.35 – 7.48 (m, 2H), 6.25 (d, J = 4, 16 Hz, 1H), 5,99 (d, J = 3.42 Hz, 1H), 2.37 (s, 3H), 1 .99 (s, 3H); MS m/e 398.9 (M+H)+.
