Reaction Steps

To a solution of 4-(piperazin-1-yl)-7-chloro-pyrido[3,2-d]pyrimidine (1.0 g, 4 mmole) in dichloromethane (40 ml), was added 3-chlorophenyl isocyanate (615 mg, 4 mmole). The reaction mixture was stirred at room temperature for 1 hour. The solvent was removed under reduced pressure, resulting in the pure title compound (1.6 g, yield 99%) as a white solid which was characterized by its mass spectrum as follows: MS (m/z): 403.1 ([M+H]+, 100).
