Mesyl Chloride (6.0 mmol) was added dropwise at 0° C. to a stirred solution of N,N-diethylaminopropanol (6.0 mmol), TEA (6.0 mmol) in anhydrous DCM (6 mL), and the mixture was stirred at the same temperature for 10 min, and at room temperature for additional 1 h. After the removal of the solvent in vacuo, the solid residue was mixed with 4-butyramidophenol (5.0 mmol), and K2CO3 (10 mmol) in anhydrous DMF (10 mL), following general procedure B. The crude product is purified using silica gel column chromatography 5% MeOH/DCM as eluent to yield 4-(N,N-diethylaminopropoxy)butyranilide (1.4 g).
