実験手順

To a mixture of 3.11 g of 2-benzyl-6-[(3R,4R)-3-hydroxy-4-methoxypyrrolidin-1-yl]pyridine and 10 ml of N,N-dimethylformamide, while stirring in an ice bath, was added dropwise 2.5 g of N-iodosuccinimide, and the resultant mixture was stirred overnight as it was. To this was added sodium sulfite and the reaction mixture was extracted with ethyl acetate-water, and the organic layer was washed with water and brine, dried over anhydrous magnesium sulfate and evaporated. The residue was purified by silica gel column chromatography (30% ethyl acetate/hexane), to give 4.19 g of the title compound.
