実験手順: To a mixture of sodium chloride (1.23 g, 21.0 mmol) and aluminum chloride (5.0 g, 38.2 mmol) at 130° C. was added 1-(4-bromophenyl)-4-chlorobutan-1-one (1.0 g, 3.82 mmol) and the resulting mixture was heated to 180° C. for 20 minutes. The mixture was allowed to cool to room temperature and poured to a cold 1N aqueous HCl solution (300 mL). The mixture was extracted several times with dichloromethane. The combined organic layers were separated, dried over magnesium sulfate, filtered and concentrated to give 5-bromo-3-methyl-indan-1-one (0.77 g, 89%). The title compound, 1-methyl-5-(3-methyl-1-oxo-2,3-dihydro-1H-inden-5-yl)-1H-pyrrole-2-carbonitrile as an orange solid (0.65 g, 76%), was prepared from 5-bromo-3-methyl-indan-1-one and 1-methyl-2-cyanopyrrole according to the same coupling procedure as described in example 1. MS (ES) m/z 251.2; Anal. Calcd for C16H14N2O: C, 76.78; H, 5.64; N, 11.19. Found: C, 76.49; H, 5.49; N, 11.10.
