HCID 866232701-(Isobutyl)-2-amino-6-(1-methyl-4-(4-fluorophenyl)-1H-imidazol-5-yl)-1H-benzimidazole methanesulfonate

Procedure

Beginning with 1-isobutyl-2-amino-6-(methyliminomethyl)-1H-benzimidazole (142 mg, 0.52 mmol), α-(p-toluenesulfonyl)-4-fluorobenzylisocyanide (302 mg, 1.05 mmol), methanol (2.5 ml), and methylamine (1.3 ml, 2M in tetrahydrofuran), 1-(isobutyl)-2-amino-6-(1-methyl-4 (4-fluorophenyl)-1H-imidazol-5-yl)-1H-benzimidazole may be prepared essentially as described in EXAMPLE 72. Treatment with 1 equivalent of methanesulfonic acid provides the title compound (114 mg).
