Reaction Conditions

Reaction Steps

To the solution of 3-bromo-4-chloro-thieno[3,2-c]pyridine (3.2 g) in dioxane (30 ml) was added 28% ammonia solution (10 ml) in an autoclave and put into the oil bath. The reaction mixture was allowed to heat up to 150° C. and stir for 4 days at 150° C. The resultant mixture was concentrated in vacuo and the residue was purified by chromatography on a silica gel column to afford 3-bromo-thieno[3,2-c]pyridin-4-ylamine (1.7 g) 1H NMR (400 MHz, DMSO-d6) ppm 7.84 (d, J=5.6 Hz, 1H), 7.78 (s, 1H), 7.27 (d, J=5.6 Hz, 1H), 6.51 (s, 2H). MS: m/z 229, 231 (M+H)+.
