Reaction Steps

To a solution of (2-chloroquinazolin-4-yl)-(4-methoxyphenyl)-methylamine hydrochloride (56 mg, 0.17 mmol) in 1 mL of DMSO and 0.5 mL of 2-propanol were added sodium cyanide (16 mg, 0.34 mmol) and 1,4-diazabicyclo[2.2.2]octane (9 mg, 0.084 mmol). The mixture was heated at 35° C. for 1 d with stirring. The solution was diluted with 5 mL of water and 10 mL of ethyl acetate. The organic layer was washed with water, then dried and concentrated. The resulting crude material was purified by silica gel column chromatography to give the title compound (34 mg, 70%). 1H NMR (CDCl3, 400 MHz) δ 7.85 (d, 1H, J=8.4 Hz), 7.64 (t, 1H, J=6.8 Hz), 7.14 (m, 3H), 6.96 (m, 3H), 3.86 (s, 3H), 3.61 (s, 3H); ESI-MS m/z 291 (M+H)+.
