Salicylaldehyde (17 g) is treated first with 6.7 g of 50% sodium hydride in 110 ml of dimethylformamide and then with 92 ml of a 2 N toluene solution of N-(3-chloropropyl)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 32.3 g of product as an oil, boiling point 155°-160° C. at 0.1-0.2 mm of Hg.
