Reaction Steps

A solution of tert-butyl (3R)-6-cyclohexyl-3-(3-{[(2-methoxy-2-oxoethyl)(methyl)amino]carbonyl}-1,2,4-oxadiazol-5-yl)hexanoate (Preparation 38) (315 mg, 0.70 mmol) in dichloromethane (10 ml) was treated with trifluoroacetic acid (5 ml) and the resulting mixture was stirred at room temperature under a nitrogen atmosphere for 2 hours. The solvent was removed under reduced pressure and the residue azeotroped from toluene. The residue was dissolved in ethyl acetate and washed with a saturated aqueous solution of sodium citrate and brine, dried over anhydrous sodium sulphate, filtered and the solvent removed under reduced pressure to afford the title compound as an oil (273 mg)
