Procedure

To the solution of [A] N-(4-{3-cyano-4-(2,4-dichlorophenyl)-5-[1-(4-fluorobenzyl)-1H-imidazol-2-yl]-2-thienyl}pyridin-2-yl)-N-(4-methoxybenzyl)acetamide (55.0 mg, 0.0806 mmol) in Acetic acid (1.0 mL, 18 mmol) was added Trifluoromethanesulfonic acid (0.10 mL, 1.1 mmol) and the mixture was stirred at r.t. for 20 hours. Methylene chloride (2.0 mL, 31 mmol) and Trifluoromethanesulfonic acid (0.10 mL, 1.1 mmol) were added and the mixture was stirred at r.t. for 20 hours. The mixture was rotovaped and azeotropped with toluene twice, dried in high vacuum. The residue was neutralized with aqueous saturated NaHCO3 to pH ˜8, extracted with EtOAc. The EtOAc solution was dried over Na2SO4, filtered, evaporated in rotavapor to give a crude residue. Chromatograph in a silica column using MeOH/DCM (0/100 to 2/98) afforded a solid product. The product was dissolved in small amount of acetonitrile and ˜5 mL water, frozen in dry ice and lyophilized to give a powder product (20 mg, yield 44.1%). LCMS: (AA) ES+, 562, 564; FS−, 560, 562. 1H NMR (400 MHz, d4-methanol) δ: 8.62 (s, 1H), 8.47-8.48 (d, J=5.27 Hz, 1H), 7.53-7.55 (dd, J=5.27, 1.76 Hz, 1H), 7.47 (d, J=2.01 Hz, 1H), 7.33-7.36 (dd, J=8.28, 2.01 Hz, 1H), 7.26-7.27 (d, J=8.28 Hz, 1H), 7.16-7.19 (dd, J=7.28, 1.51 Hz, 2H), 6.98-7.02 (m, 2H), 6.83-6.86 (m, 2H), 4.98 (s, 2H), 2.21 (s, 3H).
