실험 절차
A solution of 4 g (0.013 mole) of 2-chloro-1-[4-(4-chlorobenzoyl)-1-methyl-1H-pyrrol-2-yl]-ethanone (11) and 4.08 mL (0.039 mole) of piperidine in 60 mL 2-PrOH was heated under reflux for 1 h. The solvent was evaporated in vacuo and the residue was taken up in diethyl ether/THF, washed with water, brine, and dried (MgSO4). Evaporation of the solvent gave a tan solid which was recrystallized from 2-PrOH to give 3.65 g of product: mp 129°-130° C.; mass spectrum (Cl--CH4) m/z=345 (M+1); NMR 300 MHz (CDCl3) d 7.8 (m, 2H); 7.6 (s, 1H); 7.45 (d, 2H); 7.35 (s, 1H); 4.0 (s, 3H); 3.6 (s, 2H); 2.5 (br s, 4H); 1.6 (m, 4H); 1.4 (m, 2H). Anal Calcd for C19H21Cl2N2O2 : C, 66.18; H, 6.14; N, 8.12. Found: C, 66.25; H, 6.16; N, 8.08.
