Reaction Steps

To a solution of 4-chloro-2-(trifluoromethyl)quinazoline (8 g, 0.0344 mol) in dry dichloromethane (100 ml) under nitrogen was added methyl hydrazine (1.74 g, 0.037 mol) and the mixture was stirred at room temperature for 5 h. The reaction mixture was washed with water (2×100 ml), brine and dried. The solvent was removed under vacuum to afford 8 g (96%) of the titled compound as a yellow solid.
