Procedure

2-(2-chlorobenzoyl)-1-phthalimidopyrrole (40 g, 0.114 mmol) was suspended in 350 ml of 95% ethanol. To this rapidly stirred slurry was added 50 ml of a 40% aqueous solution of methylamine over 10 minutes. After 2.5 hours of rapid stirring the mixture was diluted with 400 ml of water and extracted with four 200 ml portions of ether. The combined extracts were washed with water, dried over anhydrous MgSO4, filtered and evaporated to an oil which solidified upon standing. Trituration of this solid with hexane and collection upon a filter yielded 23.6 g (94%) of solid, m.p. 76°-78°.
