Reaction Steps

A mixture of 1-(2-pyrimidyl)piperazine dihydrochloride (0.218 g), 2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine-6-carbaldehyde (0.20 g) and triethylamine (0.28 ml) in 1,2-dichloroethane (3 ml) was stirred for 1 hour. Acetic acid (0.040 ml) and sodium triacetoxyborohydride (0.195 g) were then added. After stirring for 24 hours the reaction mixture was diluted with dichloromethane, washed with sodium bicarbonate solution, dried (MgSO4) and the solvent removed in vacuo. The residue was purified by flash chromatography to 2-chloro-4-morpholin-4-yl-6-(4-pyrimidin-2-yl-piperazin-1-ylmethyl)-thieno[3,2-d]pyrimidine (0.115 g). 2-(1H-Indol-4-yl)-4-morpholin-4-yl-6-(4-pyrimidin-2-yl-piperazin-1-ylmethyl)-thieno[3,2-d]pyrimidine was prepared using the standard Suzuki coupling.
