In a microwave vial purged with nitrogen, a mixture of 4-(4-bromo-2-fluorophenyl)-2-propanoyl-5-[(1-propanoyl-3-azetidinyl)methyl]-2,4-dihydro-3H-1,2,4-triazol-3-one (0.37 mmol), 1,1′-bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex (0.02 mmol) and 7-quinoline boronic acid (0.39 mmol) in 1,4-dioxane (2 mL) and 2M aq potassium carbonate (2 mL) was stirred at 100° C. in an oil bath for 1 h. The reaction was cooled to room temperature and the layers were separated. The aqueous layer was acidified to pH˜5.5 using 1N HCl solution and extracted with ethyl acetate (50 mL). The organic layers were combined, dried over magnesium sulphate, and concentrated in vacuo to give a tan solid. Trituration in dichloromethane followed by treatment with hot ethanol (5 mL), which was allowed to cool to room temperature, and then filtration afforded the desired product as a white solid, 93% pure. Subsequent purification of the filtrate and white solid by reverse phase HPLC (20-60% acetonitrile/water with 0.1% NH4OH) provided the title compound as a white solid (119 mg, 74%). MS(ES)+ m/e 432.1 [M+H]+.
