1,2,3,6-Tetrahydro-4-phenylpyridine → HCID 15166841, compound

Participants

Reaction Steps

A mixture of 4-(4-pyridinyl)-1-butylchloride (Example A) (0 76 g, 4.47 mmol), 1,2,3,6-tetrahydro-4-phenylpyridine (0.796 g, 5.0 mmol), and potassium bicarbonat (1.0 g, 10 mmol) in 5 mL of acetonitrile are heated to reflux for 8 hours. The reaction is cooled to room temperature and the acetonitrile removed in vacuo. The residue is partitioned between 50 mL of water and 50 mL of chloroform. The aqueous layer is extracted again with 50 mL of chloroform and the combined organic extracts are dried over sodium sulfate and the solvent removed in vacuo. The resulting residue is chromatographed on silica gel (2% to 3% methanol, 0.1% ammonia, chloroform) to obtain 1.10 g of 4-[4-(3,6-dihydro-4-phenyl-1(2H)-pyridinyl)-butyl]pyridine as a white solid; mp 89`
