Procedure
A mixture of N-(3-amino-2,4-difluoro-benzyl)-2,2-dimethyl-propionamide (570 mg, 2.35 mmol), 1,1′-thiocarbonyldi-2(1H)-pyridone (550 mg, 2.35 mmol) and dioxane (20 mL) is stirred at reflux overnight. The reaction mixture is concentrated, diluted with DCM, filtered through a pad of silica gel and the filtrate is concentrated to give the title compound.
