Reaction Conditions

Reaction Steps

To a solution of (2-chloro-quinazolin-4-yl)-(4-methoxy-phenyl)-methyl-amine (100 mg, 0.334 mmol) in 30 ml dichloromethane cooled at −20° C. was added slowly 60 μl of BBr3 (0.668 mmol). The reaction mixture was stirred at −20° C. for 2 h then it was warmed to room temperature. It was stirred another 2 h at this temperature. The reaction mixture was diluted with ethyl acetate (50 ml) and washed with cold 5% sodium bicarbonate. The organic phase was dried and concentrated. The residue was purified by a small silica column using ethyl acetate and hexane (1:3) as eluents to give the product (57 mg, 57%). 1H NMR (CDCl3): 7.65-7.56 (m, 2H), 7.04-6.87 (m, 5H), 3.59 (s, 3H).
