Reaction Steps

A mixture of 4-acetylbenzoic acid (10.0 g, 60.9 mmol), 40% aqueous solution of dimethylamine (8.24 g, 73.1 mmol), EDC (14.0 g, 73.1 mmol), HOBT (11.2 g, 73.1 mmol) and DIEA (21.3 mL, 122 mmol) in CH3CN (150 mL) was stirred at room temperature for 15 h and concentrated. The residue was dissolved in ethyl acetate (600 mL), washed with water (2×80 mL), brine (80 mL), dried (MgSO4) and concentrated to provide 4-acetyl-N,N-dimethylbenzamide (9.80 g, 84%). MS (E+) m/z: 191 (M+H); HPLC retention time: 0.88 min (Analytical HPLC Method F).
