5 2 g of n 2 aminoethyl morpholine in 80 ml of pyridine at 5 u00b0 c over a period of 15 minutes with stirring the mixture is stirred for 30 minutes at 5 u00b0 c and 90 minutes at room temperature then 3 1 g of p chlorobenzoic acid are added and the mixture is heated for 3 hours at 90 u00b0 c this mixture is evaporated to dryness and the residue is evaporated twice more with 100 ml of toluene each time the solid residue is taken up in 100 ml of methylene chloride and 100 ml of ice water and the mixture is rendered basic with 3 n sodium hydroxide solution the phases are separated and the methylene chloride extract is washed with water dried over sodium sulfate and evaporated the residue is recrystallized from isopropanol and 1 3 g of p chloro n 2 morpholinoethyl benzamide are obtained which is identical to the product obtained in example 1 55 4 g of p chlorobenzoylaziridine and 26 5 g of morpholine are boiled in 250 ml of toluene for 2 hours under reflux the solution is then cooled to room temperature whereupon crystals separate out the solution which crystallizes is allowed to stand overnight in a refrigerator thereafter the product is removed by filtration washed with toluene and recrystallized from isopropanol and 75 9 g of p chloro n 2 morpholinoethyl benzamide are obtained which is identical to the product obtained in example 1 5 45 g of p chloro n 2 chloroethyl benzamide and 8 7 g of morpholine are stirred together for 2 hours at 100 u00b0 c the mixture is cooled to room temperature and 50 ml of water.
