Reaction Steps

A stirred mixture of 5-bromo-2,4-dichloro-6-methylthieno[2,3-d]pyrimidine (1.0 g, 3.35 mmol), ethanol (40 ml), 2-aminomethylpyridine (0.40 ml, 3.69 mmol) and triethylamine (0.50 ml, 3.69 mmol) was heated at a temperature of 60° C. for 1 hour. The reaction mixture was then cooled to ambient temperature, diluted with water (100 ml) and extracted with dichloromethane (3×50 ml). The combined organic extracts were dried (MgSO4) and the solvent removed in vacuo to give a residue. Purification by flash chromatography (silica) eluting with dichloromethane followed by 5% ethyl acetate in dichloromethane gave (5-bromo-2-chloro-6-methylthieno[2,3-d]pyrimidin-4-yl)pyridin-2-ylmethylamine as a white solid (0.99 g).
