Procedure

A solution of tert-butyl {(3R)-1-[5-(2-chlorobenzyl)-7-formyl-1,3-dimethyl-2,4-dioxo-2,3,4,5-tetrahydro-1H-pyrrolo[3,2-d]pyrimidin-6-yl]piperidin-3-yl}carbamate (132 mg) in tetrahydrofuran (4 ml) was cooled to 0° C., followed by adding thereto methylmagnesium bromide (417 μl), and the resulting mixture was stirred at 0° C. for 2 hours. A saturated aqueous ammonium chloride solution was added to the reaction solution, followed by two runs of extraction with chloroform (50 ml). The organic layer was dried over sodium sulfate and filtered and the filtrate was concentrated under reduced pressure to obtain a crude product of the title compound (167 mg).
