Reaction Steps

To a solution of (4-amino-phenyl)-(2-methyl-quinazolin-4-yl)-methylamine (48 mg, 0.18 mmol) in 250 uL of methanol and 750 uL of 1N HCl was added potassium cyanate (50 mg, 0.62 mmol) in 500 uL of water, and the mixture was stirred overnight at room temperature. The precipitated product was collected by filtration under vacuum, washed with 1 mL of cold water and dried to give the title compound (12.3 mg, 0.04 mmol, 22%). 1H NMR (DMSO): 8.75 (s, 1H), 7.60 (m, 2H), 7.45 (m, 2H), 6.99-7.13 (m, 4H), 5.92 (s, 2H), 3.45 (s, 3H), 2.59 (s, 3H).
