実験手順
[1,2,4]Triazolo[1,5-a]pyridin-2-ylmethanol (prepared as described in Example 82, step a)) (150 mg, 1.0 mmol) in ethanol (10 ml) was hydrogenated on a Parr apparatus at 50 psi over 10% palladium on carbon (150 mg) overnight. The catalyst was separated by filtration, then the filtrate was concentrated in vacuo to yield (5,6,7,8-tetrahydro-[1,2,4]triazolo[1,5-a]pyridin-2-yl)methanol as a white solid (153 mg). Data for the title compound: 1H NMR (360 MHz, CDCl3) δ 1.97 (2H, m), 2.07 (2H, m), 2.90 (2H, t, J=6.3 Hz), 3.00 (1H, br s), 4.13 (2H, t, J=6.0 Hz), 4.70 (2H, s); MS (ES+) m/e 154 [MH]+.
