Versuchsvorschrift

A mixture containing 2-(difluoromethyl)-4-fluorobenzaldehyde (47; 3.50 g, 20.1 mmol), morpholine (48; 1.9 g, 22.1 mmol) and K2CO3 (5.5 g, 40.2 mmol) in 50 mL of DMSO was stirred at 100° C. for 4 h. The resulting reaction mixture was cooled to room temperature and diluted with water (200 mL). The precipitated solids were collected by filtration and dried to afford 2-(difluoromethyl)-4-morpholinobenzaldehyde 49 (2.5 g, 52%).
