YieldReaction ConditionsOperation in experiment
67.8% To a solution of benzo [d]isoxazol-3-yl-acetic (0.86 g, 4.85 mmol) in anhydrous THF (40 mL) was added dropwise borane dimethylsulfide complex (0.58 mL, 10 M, 5.8 mmol) at 0C. The mixture was allowed to warm to room temperature and was stirred over night. MeOH (10 mL) was carefully added and when the gas evolution ceased, the mixture was heated under gentle reflux for 4 hours. The reaction mixture was concentrated in vacuo and the remainder was dissolved in dichloromethane (20 mL). An aqueous solution of Na2C03 (20 mL) was added and the aqueous layer was extracted with dichloromethane (3 x 20 mL). The combined organic layers were dried over Na(at)S04 and concentrated in vacuo. The crude product was purified by chromatography on silica gel which afforded 537 mg (67.8%) of the title compound. ¹3C NMR (125.7 MHz, CDCl3) 8 163.06,156.92, 130.27,123.65, 121.98, 121.65, 110.10, 60.34, 29.01
67.8% With dimethylsulfide borane complex; In tetrahydrofuran; at 0 - 20℃; for 4h;Heating / reflux; To a solution of (benzo[<]isoxazol-3-yl)acetic acid (0.86 g, 4.85 mmol) in anhydrous THF (40 mL) was added, dropwise at 0C, borane-dimethylsulfide complex (0.58 mL, 10 M, 5.8 mmol). The resulting mixture was allowed to warm to room temperature and was then stirred overnight. MeOH (10 mL) was carefully added and, when gas evolution had ceased, the mixture was heated under <n="101"/>gentle reflux for 4 hours. The reaction mixture was concentrated in vacuo and the resulting residue was dissolved in DCM (20 mL). An aqueous solution of Na2CC>3 (20 mL) was added and the aqueous layer was extracted with DCM (3 x 20 mL). The combined organic layers were dried over Na2SO4 and concentrated in vacuo. The crude product was then purified by chromatography on silica gel to provide 537 mg (67.8%) of the title compound.13C NMR (125.7 MHz, CDCl3): delta 163.06, 156.92, 130.27, 123.65, 121.98, 121.65, 110.10, 60.34, 29.01
