Reaction Steps

4-Chloro-5-phenyl-thieno[2,3-d]pyrimidine (1 g, 4.05 mmol) was dissolved in ethanol (15 ml) to give a yellow solution. To this was added triethylamine (1.7 ml, 12.2 mmol) and 4-piperidinemethanol (0.58 g, 5 mmol). The reaction mixture was heated to 50° C. and stirred for 1.5 hours until no 4-chloro-5-phenyl-thieno[2,3-d]pyrimidine was present by TLC. The reaction mixture was allowed to cool to room temperature before being poured over ice water (50:50 mix). The resultant precipitate was collected by filtration to give the product as a pale yellow solid (1.23 g, yield 90%). LCMS: RT=4.05 min, M+1=326.
