Reaction Steps

Chloroacetic acid chloride (0.25 ml; 3.14 mmol) is dropped slowly into a stirred solution of 3-t-Butyl-5-amino isoxazole (400 mg; 2.85 mmol) in pyridine (0.3 ml; 3.71 mmol) and dichloromethane (2 ml), cooled to 0° C. Stirring is continued for 2 h at room temperature. The reaction mixture is diluted with dichloromethane, washed twice with 1 N aqueous hydrochloric acid, twice with an aqueous solution of NaHCO3 and with water. The reaction mixture is then dried over Na2SO4, filtered and evaporated to yield 600 mg (97%) brownish solid of 11.
