Procedure

A solution of 4-(3-quinolinyl)butan-1-ol (Example E) (2.0 g, 0.01 mol), N,N diisopropyl-ethylamine (3.5 mL, 0.02 mol) and a catalytic amount of 4-dimethylaminopyridine is cooled to 0° C. and methanesulfonyl chloride (0.8 mL, 0.0105 mol) is added dropwise. The solution is stirred at 0° C. for 18 hours, and concentrated under reduced pressure. The residue is taken up in dimethylformamide (20 mL), and to this solution is added 4-phenyl-1,2,3,6-tetrahydropyridine (2.41 g, 0.015 mol) and sodium bicarbonate (3.4 g, 0.04 mol). The mixture is heated at 40° C. for 5 hours and the solvent removed under reduced pressure. The residue is partitioned between 50 mL of ethyl acetate and 50 mL of water. The aqueous layer is extracted with 50 mL of ethyl acetate and the organic extracts are dried (sodium sulfate) and the solvent removed in vacuo. The residue is chromatographed (silica gel, 2% methanol/98% dichloromethane) to give 2.15 g of the title compound; mp 92.8°-93.9° C.
