6′-Chloro-4-[2-hydroxy-2-(1-methyl-1H-benzoimidazol-2-yl)-ethylamino]-4′-trifluoromethyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-5′-carbonitrile (344.0 mg, 0.718) mmol was dissolved into 2 mL of dry DMF. To this was added a 1.09 M MeOHic solution of mercaptoacetamide (1.00 mL, 1.09 mmol) and a 1 M solution of MeOHic NaOMe (2.87 mL, 2.87 mmol). The reaction mixture was heated at 60° C. for 2 h. LC-MS indicated complete conversion to the mercaptoacetamide adduct. The reaction was then heated at 80° C. overnight. The reaction mixture was concentrated on a rotary evaporator with heating to 70° C. to give a dark orange oil. The oil was dissolved into a minimal amount of MeOH, applied to a SIO2 column and eluted with 0–10% MeOH/CH2Cl2 and 0–10% MeOH/CH2Cl2-1% NH3) to give 213.7 mg, 55.8%, of the title compound.
