Reaction Steps
To a solution of (3-(trifluoromethyl)isoxazol-5-yl)methanol (2.5 g, 15 mmol) in dimethylformamide (25 mL) was added drop wise tribromophosphine (4.64 g 17.1 mmol, 1.15 eq) and the mixture was stirred at 0° C. for 15 min and at ambient temperature for 2 h. The reaction mixture was partitioned between 10% sodium bicarbonate and dichloromethane. The phases were separated and the organic phase was washed with water and passed over a plug of silica eluting with dichloromethane. The UV active product fractions were collected and evaporated to yield the title compound as colorless oil (2.04 g 59.3%), MS 229 and 231(M)+.
