Procedure

A solution of tert-butyl {(3R)-1-[5-(2-chlorobenzyl)-7-cyano-3-methyl-2-(methylsulfonyl)-4-oxo-4,5-dihydro-3H-pyrrolo[3,2-d]pyrimidin-6-yl]piperidine-3-yl}carbamate (110 mg), 3-ethoxyphenol (31 μl) and potassium carbonate (39 mg) in N,N-dimethylformamide (2 ml) was stirred at 50° C. for 1 hour. After the reaction solution was allowed to cool, a saturated aqueous ammonium chloride solution was added thereto, followed by extraction with ethyl acetate. The organic layer was washed with water and a saturated aqueous sodium chloride solution, dried over sodium sulfate and then filtered and the filtrate was concentrated under reduced pressure. The resulting residue was purified by a silica gel column chromatography (hexane/ethyl acetate=3/1 to 1/1) to obtain the title compound (86 mg) as a white solid.
