Reaction Steps

A solution 2-((1R)-1 -{2-[(benzyloxy)amino]-2-oxoethyl}4-cyclohexylbutyl)-N-[2-(dimethylamino)ethyl]-5-methyl-1,3-oxazole-4-carboxamide (Preparation 98) (193 mg, 0.39 mmol) in ethanol (10 ml) was treated with ammonium formate (244 mg, 3.90 mmol) and 5% palladium on barium sulphate (100 mg) and heated at 43° C., under a nitrogen atmosphere for 2 hours. The reaction mixture was filtered and the solvent removed under reduced pressure. The residue was purified by column chromatography on silica gel eluting with a gradient system of 98:2:0.2 (dichloromethane:methanol:ammonia) gradually changing to 90:10:1 (dichloromethane:methanol:ammonia) to afford the title compound as a white solid (80 mg).
