Reaction Conditions

Reaction Steps

4-Chloro-5-phenylthieno[2,3-d]pyrimidine (1.5 g, 6.1 mmol), piperidine-4-carboxylic acid (0.86 g, 6.7 mmol) and triethylamine (2.6 mL, 18 mmol) were suspended in dry ethanol (15 mL). The reaction was heated at 140° C. in a microwave for 10 min. The reaction was partitioned between water and DCM. The product was purified by column chromatography using a gradient of 10% methanol in DCM to 100% methanol to give the target compound as an off-white solid (yield=2.1 g). LCMS [M+H]+=440; RT=4.04 min.
