Reaction Conditions

Reaction Steps

To a solution of 2-methoxy-5-(5H-pyrrolo[2,3-b]pyrazin-6-yl)-phenol [0.5 g, Example 28]in dimethylformamide (10 mL) and cesium carbonate (0.67 g) was added ethyl chloroacetate (0.025 g). The reaction mixture was heated at 50° C. overnight. After cooling, the dimethylformamide was removed in vacuo and the residue partitioned between ethyl acetate and water. The organic fraction was dried over sodium sulfate, evaporated and subjected to flash column chromatography on silica eluting with 2.5% methanol in dichloromethane. This product was further triturated with a mixture of ethyl acetate and pentane to give the title compound as a white solid, m.p. 183-184° C. MS: 328 (MH+).
