実験手順

In 7.5 ml of N,N-dimethylformamide was dissolved 2.5 g of 4-[3-(4-tert-butoxycarbonylamidinophenoxy) propyl]-2,3-dioxopiperazine, and to the solution were added 6.1 g of diphenylmethyl 3-(3-pyridyl)acrylate and 0.48 ml of 1,8-diazabicyclo[5.4.0]undec-7-ene. The resulting mixture was stirred overnight at room temperature and distilled under reduced pressure to remove the solvent. To the resulting residue were added 80 ml of ethyl acetate and 60 ml of water and the pH was adjusted to 7 with 2N hydrochloric acid. The organic layer was separated, washed with water and then a saturated aqueous sodium chloride solution, and then distilled under reduced pressure to remove the solvent. The resulting residue was purified by a silica gel column chromatography (eluent; chloroform: methanol=20:1) to obtain 2.34 g of diphenylmethyl 3-[4-[3-(4-tert -butoxycarbonylamidinophenoxy)propyl]-2,3-dioxopiperazin-1-yl]-3-(pyridin-3-yl)propionate as a colorless oil.
