Reaction Conditions

Reaction Steps

Sodium hydroxide (10.6 mg, 0.264 mmol) was added to a solution of 54 mg (0.176 mmol) of (R)-(4-bromophenyl)(3-hydroxypyrrolidin-1-yl)methanone in dimethyl sulfoxide (1 ml) synthesized in the same manner as in step (i) of Reference Example 8, 0.11 ml (1.76 mmol) of methyl iodide was then added thereto, and the mixture was stirred at 100° C. for 20 hr. A saturated aqueous sodium hydrogencarbonate solution was added thereto, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine in that order, was dried over anhydrous sodium sulfate, and was then filtered. The filtrate was concentrated under the reduced pressure, and the residue was purified by preparative thin layer chromatography (chloroform:methanol:28% aqueous ammonia=9:2:0.2) to give 45 mg (yield 90%) of the title compound.
