反応手順
500 mg (1.42 mmol) of sarcosine benzyl ester p-toluenesulfonate, 478 mg (2.13 mmol) of 2-(tert-butoxycarbonylamino)-ethyl bromide, and 0.25 mL (2.13 mmol) of diisopropyl-ethylamine were dissolved in methylene chloride (10 mL), and then stirred at room temperature for approximately three days. After completion of the reaction, the reaction solution was concentrated and the residue obtained was purified by silica gel column chromatography (ethyl acetate) to yield 175 mg (38%) of {[2-(tert-butoxycarbonylamino)-ethyl]-methyl-amino}-acetic acid benzyl ester as a colorless viscous oil.
