반응 단계

A mixture of ethyl 2-(3,5-dimethoxyphenyl)-2-oxoacetate (1 g, 4.2 mmol) and 2-chloro-N4-methylpyrimidine-4,5-diamine (600 mg, 3.8 mmol) in ethanol (100 mL) and acetic acid (2.5 mL) was stirred at 80° C. for 48 h and cooled to RT (5° C.). The mixture was diluted with dichloromethane and washed with brine. The organic layer was directly concentrated and purified by chromatography on silica gel to give the title compound (700 mg, 50%). MS (ES+) C15H13ClN4O3 requires: 332, 334. Found: 333, 335 [M+H]+.
