실험 절차

Salicylaldehyde (34 g) is treated first with 13.4 g of 50% sodium hydride in 220 ml of dimethylformamide and then with 185 ml of a 2 N toluene solution of N-(2-chloroethyl)morpholine. The mixture is heated at 105°-110° C. for 4 hours, cooled and poured into 300 ml of water. The product is extracted three times with ether. The extracts are combined, dried, concentrated on a rotary evaporator and the residue distilled to give 56.6 g of product as an oil, boiling point 145°-150° C. at 0.05-0.1 mm of Hg.
