Procedure

After adding 0.381 g (1.3 equivalents) of sodium hydride (60% dispersion, Aldrich) to a solution of 2.46 g of the 6-(4-benzyloxyphenyl)-4-chloro-7H-pyrrolo[2,3-d]pyrimidine synthesized in Production Example 153-3 in dimethylformamide (30 ml), the mixture was stirred at room temperature for 40 minutes, 1.68 ml (1.3 equivalents) of 2-(chloromethoxy)ethyltrimethylsilane was added, the mixture was stirred at room temperature overnight, and then 20 ml of water and 1 ml of acetic acid were added and liquid separation and extraction were performed with an ethyl acetate: tetrahydrofuran (5:1) mixed solvent. The organic layer was dried over sodium sulfate, concentrated and subjected to NH silica gel column chromatography (ethyl acetate) to obtain 2.83 g of the title compound.
