実験手順
To a mixture of 2-bromo-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidine (0.1 g, 0.47 mmol) and triethylamine (0.2 mL) in 2 mL of DCM, at 0° C., was added MsCl (0.1 mL). The mixture was stirred at room temperature for 1 h then diluted with 20 mL of DCM and washed with a mixture of saturated NaHCO3 (15 mL) and water (15 mL). The DCM was evaporated to afford the crude 59a.
