Participants

Reaction Steps

To a mixture of N-(2,6-difluorophenyl)-3-oxobutanamide obtained in Step A (5.00 g) and N,N-dimethylformamide (20 mL) was added dropwise 1,1-dimethoxy-N,N-dimethylmethanamine (6.32 mL) over 20 min at room temperature, and the reaction mixture was stirred overnight at room temperature. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (methanol/ethyl acetate) to give the title compound (3.70 g).
