Procedure

35.0 g of N-(1'-methoxycarbonyl-ethyl)-2,6-dimethyl-3-acetoxymethylaniline and 13.3 g of sodium carbonate were placed into 250 ml of toluene, and 20.0 g of methoxyacetic acid chloride, dissolved in 50 ml of toluene, were slowly added. After the exothermic reaction had subsided, the temperature was held at 45° C. for 7 hours by means of a water-bath. The cooled reaction mixture was filtered, and the filtrate was concentrated in a rotary evaporator. The oily residue was distilled: b.p. 167°-171° C. at 0.07 bar.
