To a round bottom flask was added (S)-4-(3-(1-(benzyloxy)ethyl)-8-(4-chlorophenyl)-5-((2-methyl-6-(trifluoromethyl)pyridin-3-yl)methyl)-6-oxo-5,6-dihydro-[1,2,4]triazolo[4,3-b]pyridazin-7-yl)benzonitrile (30 mg, 0.0458 mmol), CH3CN (2 ml) and TMSI (244 mg, 1.22 mmol). The reaction was stirred at 60° C. under argon for 4 days. After this time, the reaction mixture was with EtOAc (50 ml). The resulting organic solution was wash with water (20 ml), 10% NaHSO3(20 ml) and saturated NaCl (20 ml). The organic layer was dried over MgSO4, filtered and concentrated. The crude product was purified by silica gel column chromatography (8 g silica gel) eluting with a gradient of 0-80% EtOAc/Hex to give product (R)-4-(8-(4-chlorophenyl)-3-(1-hydroxyethyl)-5-((2-methyl-6-(trifluoromethyl)pyridin-3-yl)methyl)-6-oxo-5,6-dihydro-[1,2,4]triazolo[4,3-b]pyridazin-7-yl)benzonitrile as a white solid (8 mg, 31% yield).
