Procedure
The methaneamine derivative was synthesized essentially according to the procedure described for the synthesis of 1-amino-1-(3-pyridyl)-2-(3-tetrahydrofuranyl)-ethane. Thus, tetrahydropyran-4-ol methane sulfonate (0.99 g, 5.5 mmol), prepared according to the procedure of Suto et al., J. Med. Chem., 34:2484 (1991), was treated with the imine anion generated by reacting N-(diphenylmethylidene)-3-(aminomethyl)pyridine (1.36 g, 5.0 mmol) with LDA (5.5 mmol in 5.0 mL tetrahydrofuran). A work up similar to the one described for the synthesis of 1-amino-1-(3-pyridyl)-2-(3-tetrahydrofuranyl)-ethane, followed by purification by column chromatography (15% methanol in chloroform) yielded 1-amino-1-(3-pyridyl)-1-(4-tetrahydropyranyl)-methane (499 mg) in 52% yield.
