Procedure

To a solution of 2-[1-(2-chlorophenyl)-1-methylethyl]-1-[3′-(methylsulfonyl)biphenyl-4-yl]-4-pyrrolidin-2-yl-1H-imidazole and MeOH was added formaldehyde, followed by AcOH. The reaction was stirred for 20 min, NaCNBH3 was added to the reaction mixture and was continued to stir for another 30 min. After a routine aqueous work up, the crude product was purified by prep HPLC to give 2-[1-(2-chlorophenyl)-1-methylethyl]-4-(1-methylpyrrolidin-2-yl)-1-[3′-(methylsulfonyl)biphenyl-4-yl]-1H-imidazole: 1H NMR (CD3OD): δ 1.6 (m, 3H,), 1.8 (s, 1H), 1.9 (s, 3H), 2.2-2.5 (m, 4H), 2.8 (s, 3H), 3.2 (s, 3H), 3.6 (br, 1H), 4.7 (m, 1H), 7.1 (m, 1H), 7.2 (m, 5H), 7.4 (s, 1H), 7.7 (m, 3H), 8.0 (m, 2H), 8.2 (m, 1H); LC/MS M+H 534 (observed).
