Procedure

To a mixture of diethylamine (89.1 mL), triethylamine (120.2 mL) and CH2Cl2 (500 mL) cooled in an ice-bath was added dropwine p-anisoyl chloride (133.8 g) over 40 minutes. The reaction mixture was stirred at room temperature for 40 minutes, the mixture was filtered, washed with ether and the solvent was removed in vacuo. Ether was added, then water to the residue, then the organic layer was separate and washed with 5% NaoH, then in HCl, then brine and then was dried over Na2SO4. The solvent was removed in vacuo and the residue was purified by kugelrohr distillation at 140°-180° C. under high vacuum to afford 163.8 g of 4-methoxy-N,N-diethylbenzamide, m.p. 40°-42° C.
