Reaction Steps

6-Acetamido-3-methyl-1,2-benzisoxazole (571 mg, 3.00 mmol) was dissolved in dry THF (18 mL). 2M of LDA (3.1 mL, 6.2 mmol) was dropwise added to the solution for 10 minutes under nitrogen atmosphere at −78° C. A solution of 4-iodomethyl-5-isopropyl-2-(2,4-dichlorophenyl)oxazole (1.19 g, 3.00 mmol) in THF (3.0 mL) was dropwise added to the resulting mixture for 7 minutes. The mixture was stirred for 1 hour under the same conditions. The mixture was allowed to room temperature. A saturated aqueous ammonium chloride solution and ethyl acetate were added to the mixture. The organic layer was washed with water and saline, and dried over anhydrous sodium sulfate. Ethyl acetate was removed under reduced pressure. The residue was purified by column chromatography on silica gel with chloroform/methanol (80/1) to give the desired compound (904 mg) as pale yellow oil (yield 70%).
