Versuchsvorschrift

To a solution of 4-(4-{[5-nitro-2-(2-trifluoromethoxy-benzylamino)-pyrimidin-4-ylamino]-methyl}-cyclohexylamino)-butyric acid methyl ester (39 mg, 0.072 mmol) in 6:1 MeOH/water (0.7 mL) was added LiOH (9 mg, 0.375 mmol) and the mixture stirred at room temperature overnight. The resulting suspension was diluted with MeOH (1 mL) and stirred at room temperature for a further 2 h. The reaction mixture was concentrated in vacuo and the remaining aqueous residue treated with 2 N HCl until the mixture reached pH 5-6. The resulting solid was filtered and washed with water. The material was subjected to semi-preparative to separate the title compound [7 mg, 13%, m/z 527 (M+1)+] and 1-(trans-4-{[(5-nitro-2-{[2-(trifluoromethoxy)benzyl]amino}pyrimidin-4-yl)amino]methyl}cyclohexyl)pyrrolidin-2-one [15 mg, 41%, m/z 509 (M+1)+].
