Reaction Conditions

Reaction Steps

A mixture of 4-methylthiopyrido[3,4-d]pyrimidine (74 mg, 0.41 mmol) (see a previous experimental), and benzylamine (1 mL) is heated to 10° C. for 2 h. On cooling the mixture is concentrated under reduced pressure and purified directly by preparative tlc on silica gel eluting with CH2Cl2, to yield 4-(benzylamino)pyrido[3,4-d]pyrimidine (21.2 mg, 20%). 1H NMR (DMSO) δ 9.21 (1H, t, J=5.8 Hz), 9.19 (1H, s), 8.63 (1H, d, J=5.8 Hz), 8.58 (1H, s), 8.20 (1H, d, J=5.1 Hz), 7.41-7.30 (4H, m), 7.26 (1H, t, J=7.1 Hz).
