실험 절차

A solution of 2-((1R)-1-{2-[(benzyloxy)amino]-2-oxoethyl}-4-cyclohexylbutyl) —N,N-dimethyl-1,3-oxazole-4-carboxamide (Preparation 66) (100 mg, 0.23 mmol) in ethanol (5 ml) was treated with 5% palladium on barium sulphate (50 mg), pressurised to 1 atm with hydrogen in a sealed vessel and the mixture was stirred at room temperature for 2 hours. The solution was filtered through Arbocel® and the solvent removed from the filtrate under reduced pressure. The residue was azeotroped from dichloromethane (×3) then dichloromethane:ether (1 ml:4 ml) to afford the title compound as a foam (75 mg).
