Reaction Steps

1-(3-Fluorophenyl)ethanone (17 g, 0.123 mol), dimethylamine (13.7 g, 0.172 mol), and paraformaldehyde (5.5 g, 0.185 mol) were suspended in ethanol (50 mL), and conc HCl solution (0.3 mL) was added. The mixture was heated at reflux overnight. The solvent was removed under vacuum, and the residue was washed with EtOAc (3×) to give 3-(dimethylamino)-1-(3-fluorophenyl)propan-1-one (20.7 g, 88%), which was used for the next step without purification.
