실험 절차
A solution of 17.5 g (0.08 mole) of (4-chlorophenyl)(1-methyl-1H-pyrrol-2-yl)methanone, 14.4 g (0.088 mole) of isonicotinoyl chloride and 26.6 g of aluminum chloride (0.2 mole) in 280 mL of DCE was heated under reflux for 16 h. After cooling, the mixture was partitioned between CH2Cl2 and dilute NaOH solution. The organic layer was dried and the solvent was evaporated in vacuo. The residue was triturated with ether. The resulting solid was recrystallized from 2-PrOH to give 7 g (27%) of the title compound, mp 174-175° C. ES-MS m/z=325 (M++H). 1H NMR (300 MHz, CDCl3) δ 4.1 (s, 3H); 7.1 (s, 1H); 7.3(dd, 2H); 7.42 (dd, 2H); 7.45 (s, 1H); 7.8 (dd, 2H); 8.8 (dd, 2H). Anal calc'd for: C18H13ClN2O2: C, 66.57; H, 4.03; N, 8.63. Found: C, 66.34; H, 3.94; N, 8.53.
