실험 절차

N,N-Diisopropylethylamine (1.93 ml, 11.10 mmol) and chloromethylmethyl ether (0.56 ml, 7.40 mmol) were added under cooling on ice to a solution of 4-(3-{[tert-butyl(dimethyl)silyl]oxy}-2-hydroxypropyl)-6-methoxypyrido[2,3-b]pyrazin-3(4H)-one (1.35 g, 3.70 mmol) in dichloromethane (20 ml) and the mixture was stirred for 24 hours. The reaction solution was diluted with dichloromethane and washed with water. The organic layer was dried over anhydrous sodium sulfate, the solvent was removed under reduced pressure and the residue was purified by silica gel column chromatography (hexane/ethyl acetate) to yield 1.02 g (67%) of the title compound in the form of a yellow oily product.
