To a mixture of 6-amino-7-methyl-2-propyl-3-[2'-(aminosulfonyl)[1,1']biphenyl-4-yl]methyl-3H-imidazo[4,5-b]pyridine (80 mg, 0.15 mmol) in pyridine (0.5 mL) at 0° C. was added butylsulfonyl chloride (0.02 mL, 0.15 mmol). The mixture was stirred for 1 h, then 1 mL of MeOH was added and the mixture was concentrated. Purification (SiO2, 5% MeOH-EtOAc) gave 50 mg of 6-[(Butylsulfonyl)amino]-7-methyl-2-propyl-3-[2'-(aminosulfonyl)[1,1']-biphenyl-4-yl]methyl-3H-imidazo[4,5-b]pyridine as a solid.
