Procedure: To a solution of 2-(2-chloroethoxy)ethanol 14 (5 mL, 47.4 mmol) in N,N-dimethylformamide (35 mL) was added potassium phthalimide 2 (8.8 g, 47.51 mmol), and the reaction mixture was stirred for 20 h at 70° C. The mixture was concentrated and then diluted with dichloromethane (300 mL), and the organic layer was washed with water, dried, and concentrated. The residue was purified by flash column chromatography (3:2 to 2:3 hexane-ethyl acetate) to give compound 15 as a white solid (7.15 g, 64.17%) having an RF of 0.12 (solvent 3:2 hexane-ethyl acetate). See FIG. 9. The mixture was concentrated diluted with dichloromethane (300 mL) the organic layer was washed with water dried concentrated The residue was purified by flash column chromatography (3:2 to 2:3 hexane-ethyl acetate)

Procedure: A mixture of 400 mg (0.746 mmol) N-(3,5-bis-trifluoromethyl-benzyl)-N-methyl-6-piperazin-1-yl-4-o-tolyl-nicotinamide (Example 53), 0.18 ml (1.7 mmol) 2-(2-chloroethoxy)-ethanol and 0.189 g (1.35 mmol) potassium carbonate in 8 ml acetonitrile was stirred at 85° C. for 48 h. After cooling to room temperature 40 ml 1 N sodium hydroxide solution were added. Extraction with 3 60-ml portions of dichloromethane, drying with sodium sulfate and concentration gave 528 mg of the crude product. Flash column chromatography afforded 300 mg (64.4%) of the title compound as a light-brown solid. were added Extraction with 3 60-ml portions of dichloromethane drying with sodium sulfate and concentration gave 528 mg of the crude product
