実験手順

The compound of formula (In), wherein R11 is 4-cyano, m is 1, W=NH, and the bonds depicted as wavy bonds define the 7aS,6S stereoisomer, was prepared as follows. To a solution of (7aS)-2-(3,5-dichloro-phenyl)-tetrahydro-pyrrolo[1,2-c]imidazole-1,3,6-trione (0.5 g) (0.0017 mol) (Preparation 20), in 50 mL of DCM was added molecular sieves 4A, 4-cyanobenzyl amine (0.27 g) (0.002 mol), then NaBH(OAc)3 (0.54 g) (0.00255 mol.). The reaction mixture was stirred overnight at RT and then the insoluble material eliminated. After evaporating the solvent, the residue was purified by SiO2 chromatography (eluent: DCM/MeOH 98/2) to afford the titled compound and its stereoisomer. 7aS,6S stereoisomer (70 mg). NMR (CDCl3, 200 MHz): 7.45 (2H, d), 7.3 (1H, m), 7.2-7.1(4H, m), 4.25 (1H, dd), 4.05 (1H, d), 3.65 (2H, dd), 3.4(1H, m), 3.02 (1H, dd), 2.35-2.2 (1H, m), 2.0 (1H, bd).
