実験手順
2-Methoxyethylamine (0.278 ml, 3.2 mmol) was added at room temperature to a solution of 5-bromo-2-methanesulfonyl-pyrimidine-4-carboxylic acid ethyl ester (0.2 g, 0.65 mmol) in dichloromethane (5 ml). Stirring was continued at 45° C. for 2 hours. The solvent was evaporated and the crude product was purified by silica gel chromatography using an ethyl acetate/heptane eluent to yield the title compound as colorless oil (0.175 g, 89%).
