A dichloromethane suspension (3.0 ml) of C-(3-aminomethyloxetan-3-yl)methylamine (411 mg, 3.54 mmol) prepared according to the method described in J. Org. Chem., (1985),50(17), 3211; and Japanese Patent Application Kokai Publication No. (JP-A) S61-69784 (unexamined, published Japanese patent application) was cooled to 0° C., and a dichloromethane solution (3.0 ml) of triphenylmethyl chloride (246 mg, 0.88 mmol) was added thereto. The mixture was stirred at 0° C. for 30 minutes, and then at room temperature for one hour. A saturated aqueous sodium bicarbonate solution (1.0 ml) and water (15 ml) were added to the solution. The mixture was extracted three times with dichloromethane (20 ml). The organic layers were combined together, and dried over anhydrous sodium sulfate. After the inorganic salt was removed by filtration, the filtrate was concentrated under reduced pressure. The resulting crude product was purified by silica gel column chromatography (developing solvent: dichloromethane:methanol=20:1) to yield (3-aminomethyloxetan-3-ylmethyl)tritylamine (162 mg) as a white amorphous material.
