Procedure

A solution of diethyl [(3-bromo-7-cyano-2-naphthyl)(difluoro)methyl]phosphonate (2.2 g) in dichloromethane (5 mL) and TMSBr (7 mL) was stirred overnight and concentrated. The residue was co-evaporated with dichloromethane (2×), ethanol/water (2×) and then dissolved in 20 mL of methanol. Ammonia (30%) was then added with vigorous stirring and the mixture was concentrated and co-evaporated with methanol (3×). The solid residue was washed with ether to give the desired product as a white powder. MS (−ESI): m/z 360.0 and 361.9 (M−1).
