실험 절차

A solution of N-benzyloxycarbonyl-(L)-alanine (63 mg, 0.28 mmol) in dichloromethane (4 ml) at −20° C. was treated with N-[3-amino-9,10,11-trimethoxy-6,7-dihydro-5H-dibenzo[a,c]cyclohepten-5-yl]acetamide (100 mg, 0.28 mmol), (V. Fernholz Justus Liebigs Ann., 1950, 568, 63–72), and 1,3-dicylcohexylcarbodiimide (134 mg, 0.31 mmol) and the solution stirred for 16 hours at ambient temperature. Solvent was evaporated under reduced pressure and the residue chromatographed on silica gel, eluting with ethyl acetate to give a white solid which was triturated with diethyl ether. The title compound (85 mg) was obtained as a white solid.
