To a suspension of 1-adamantan-2-yl-3-(4-methoxy-2-methyl-phenyl)-urea 1.56 g (4.88 mmol) in DCM 20 ml was added at −78° C. under argon a solution of boron tribromide 1M in DCM 14.67 ml (14.67 mmol). The reaction mixture was stirred at −78° C. for 1 h then allowed to reach room temperature. Water 60 ml was added, the precipitate was filtered, washed with water and dried under vacuum to give 1.36 g (92%) a white solid.
