実験手順

A solution containing [2-(2-chlorobenzoyl)-1H-pyrrol-1-yl]-methyl-carbamic acid, ethyl ester (29.4 g, 91 mmol) and sodium hydroxide (11 g, 275 mmol) in 50% aqueous ethanol was heated under reflux for 16 hours. The excess ethanol was evaporated and the solution was adjusted to pH 7 with 10% HCl. The resultant slurry was extracted with three 100 ml portions of DCM, dried (MgSO4), filtered, and evaporated to give 22 g of solid. This solid was charcoaled and recrystallized from ether-hexane to give 21 g (93%) of powder, m.p. 107°-108°.
