실험 절차

A mixture of methyl 4-(5-amino-1-methylindol-3-ylmethyl)-3-methoxybenzoate (D) (0.57 g.), cyclopentylacetic acid (0.23 g.), 4-(dimethylamino)pyridine (0.22 g.), and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.343 g.), was dissolved in dichloromethane (25 ml.), under an atmosphere of nitrogen, and stirred at room temperature for 18 hours. The mixture was poured into 1M hydrochloric acid (25 ml.), the separated aqueous layer extracted with dichloromethane (3×25 ml.), the combined organic extracts washed with water, brine, dried (MgSO4) and evaporated. The residual oil was crystallized from ethyl acetate to give the title compound (0.555 g. 73%) as a white powder; m.p. 180°-181° C.; partial NMR (250 MHz, DMSO-d6 ): 1.17(m,2H); 1.4-1.8 (m,6H); 2.25(m,3H); 3.70(s,3H, NMe); 3.82(s,3H, OMe); 3.92(s,3H, OMe); 3.97(s,2H, ArCH2); 9.62(br s, 1H, NH).
