To a solution of (1R,2S,5R)-5-methyl-2-(propan-2-yl)cyclohexyl N-[(1S,2S)-2-methyl-2-{[5-(trifluoromethyl)pyrazin-2-yl]amino}cyclopentyl]carbamate (1.03 g, 2.33 mmol) in acetic acid (8 ml) was added HBr (6M, 1.94 ml, 11.64 mmol). The reaction was sealed and heated to 90° C. for 20 hours. To this was added further HBr (6M, 1.00 ml, 6.00 mmol) and the reaction was heated at 90° C. for 36 hours and was then concentrated in vacuo. The crude product was purified by reverse phase chromatography (C18 silica, 0-100% water (with 0.05% ammonia)/acetonitrile) to afford the title compound.
