HCID 6228DimethylformamideSolvent

Procedure

334 mg of 1-benzhydryl-3-cyclopropylazetidin-3-ol was dissolved in dimethylformamide, and 72 mg of 60% sodium hydride was added thereto, and the mixture was stirred at room temperature for 30 minutes. 112 μl of methyl iodide was added thereto, and the mixture was further stirred at room temperature for 2 hours. To the reaction solution was added water and the mixture was subjected to extraction with diethyl ether, and dried over magnesium sulfate. The solvent was distilled off under reduced pressure, and then the obtained residue was purified by silica gel column chromatography to obtain 280 mg of the objective compound.
