Reaction Steps

To a solution of 0.155 g (0.424 mmol) of (Z)-6-(4-stilbenesulfonyl)-4,5,6,7-tetrahydrofuro[2,3-c]pyridin in 10 ml of acetic acid, 57 mg (0.64 mmol) of 50% aqueous dimethylamine and 52 mg (0.64 mmol) of 37% aqueous formaldehyde were added, followed by stirring at 100° C. for 0.5 hours. After the solvent was distilled off under reduced pressure, the residual solution was alkalified with aqueous sodium hydroxide and extracted with ethyl acetate 3 times. The combined organic layer was dried over anhydrous magnesium sulfate; the solvent was distilled off under reduced pressure. The resulting crude product was purified by silica gel column chromatography (ethyl acetate to ethyl acetate/methanol=4/1) to yield the desired product.
