Procedure

Using essentially the same procedure described in Example 1, steps a-c, and employing 3-bromo-4-fluoro-1-ethynylbenzene the racemic mixture of 2-amino-5-(3-bromo-4-fluorophenyl)-5-[4-(difluoromethoxy)phenyl]-3-methyl-3,5-dihydro-4H-imidazol-4-one was obtained and separated by chiral chromatography technique (Chiralcel OJ, 0.46×10 cm, using 15% ethanol in 85% hexane and diethylamine as the mobile phase) to give the title enantiomer, MS m/e (M+H)+ 332; 1H NMR (400 MHz, DMSO-d6) 2.94 (s, 3H), 6.74 (brs, 2H), 7.1 (d, J=8.75 Hz, 2H), 7.13-7.65 (m, 5H), 7.67 (d, J=2.2 Hz, 1H); [a]25=−22 (C=1% in MeOH).
