Procedure

2-Chloro-N-(3,4,5-trimethoxyphenyl)thieno[3,2-d]pyrimidin-7-amine (30 mg, 0.085 mmol) was dissolved in N,N-dimethylformamide (1 mL) and sodium hydride (5.2 mg, 0.13 mmol) was added at 0° C. After stirring for 10 minutes and adding iodomethane (15 mg, 0.10 mmol), the mixture was stirred for an hour, diluted with ethyl acetate, and washed with brine. The organic layer was dried with magnesium sulfate, filtered with celite, and then concentrated. The target compound (28 mg, 89% yield) was obtained without purification.
