The reaction vessel was then placed under a hydrogen atomsphere for two hours. The reaction mixture was then passed through a CELITE™ pad and then partitioned between water and methylene chloride. The aqueous fraction was extracted twice with methylene chloride. The organic fractions were combined, washed with water and then brine, and dried over sodium sulfate. The solvents were removed in vacuo. The desired title product was further purified by chromatography.
