Reaction Steps

A solution of ethyl 5-{(1R)-1-[2-(tert-butoxy)-2-oxoethyl]-4-cyclohexylbutyl}-1,2,4-oxadiazole-3-carboxylate (Preparation 3) (560 mg, 1.42 mmol) in ethanol (2 ml) was treated with N,N,N′-trimethylethylenediamine (900 □1,0.91 mmol) and the resulting mixture was heated at 85° C. in a sealed tube for 4.5 hours. The solvent was removed under reduced pressure and the residue was purified by column chromatography on silica gel eluting with a system of 95:5:0.5 (dichloromethane:methanol:ammonia) to afford the title compound as a colourless oil (632 mg).
