실험 절차

A mixture of 62.69 g (0.256 mole) of diphenyl-4-pyridylmethane and 6.4 g of 10% palladium on carbon (0.0060 mole) in 300 ml of glacial acetic acid and under an atmosphere of hydrogen (44 psi) was shaken on a Parr apparatus at 85° for 4 days. The reaction mixture was filtered, and the solvent was removed in vacuo from the filtrate. The residue was partitioned between methylene chloride and dilute sodium hydroxide. The methylene chloride solution was dried over magnesium sulfate, and the solvent was removed in vacuo to give a solid. This was dissolved in a mixture of methanolacetronitrile, and excess ethereal hydrogen chloride was added. A precipitated was collected to give 59.13 g (80.3%) of slightly impure title compound as a white crystalline solid, m.p. 273°-274° C. Part of this was recrystallized from methanol-ether to give an analytically pure sample, m.p. 275.5°-277° C.
