Procedure

70 g of p-chlorobenzaldehyde and 105 g of morpholine were heated to boiling in 260 g of methylcyclohexane in a water separator. Over the course of 45 minutes, 8.4 ml of water were removed azeotropically. The mixture was left to cool with slow stirring. At 58° C., the solution was seeded, and very fine crystals slowly precipitated out. The mixture was cooled in an ice bath to +5° C. After a post-stirring time of 1 hour, the solid which had precipitated out was filtered off with suction. The white product was washed with 2×50 ml of methylcyclohexane and dried overnight in a drying cabinet at 20° C. and 100 mbar. 129.2 g of product were obtained in the form of white crystals (87% of theory).
