Reaction Steps

To a stirred slurry of 0.76 g (20 mmoles) of lithium aluminum hydride in 25 ml THF was added dropwise a solution of 0.58 g (2 mmoles) of ethyl 4,5-diphenylpyrrole-3-carboxylate in 5 ml THF. The mixture was heated at reflux overnight. After cooling, 0.8 ml water, 2.4 ml 15% sodium hydroxide solution and 0.8 ml water were added dropwise. The solids were removed by filtration and the filtrate concentrated by rotary evaporation. The crystalline residue was purified by chromatography on 50 g silicic acid (CC-7) eluting with hexane/toluene (90/10) to give 0.25 g of product, m.p. 163°-164° C.
