Reaction Steps

2.2 g of 2-benzyl-3-methoxymethyloxy-6-[(3S)-3-hydroxy-2-pyrrolidinone-1-yl]pyridine (Example 138a) was dissolved in 20 ml of ethyl acetate, and 2.3 g of 3-nitrobenzenesulfonyl chloride, 183 mg of 4-dimethylaminopyridine and 3 ml of triethylamine were added thereto, followed by stirring at room temperature overnight. Then, water was added thereto, and the mixture was extracted with ethyl acetate. The organic phase was further washed with brine, dried over anhydrous sodium sulfate and the solvent was removed. The residue was subjected to silica gel column chromatography using 25-33% ethyl acetate/hexane as an eluent, to give 3.5 g of the target compound.
