Reaction Steps

(S)-4-{[Ethyl-(2-trifluoromethyl-pyrimidin-4-yl)-amino]-methyl}-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (0.339 g, 0.84 mmol) was dissolved in dioxane (6 ml), aqueous hydrochloric acid (4N, 6 ml) was added and the mixture was stirred at 60° C. for 3 hours. The solvent was evaporated and the residue was dissolved in dichloromethane. A solution of ammonia in methanol (2N, 2 ml) was added and the mixture was evaporated over Isolute® Flash-NH2 silicagel. Chromatography (column: Isolute® Flash-NH2 from Separtis; eluent: ethyl acetate/MeOH=95:5) yielded a light yellow liquid, (0.19 g, 86%); MS (ISP): 265.3 ((M+H)+).
