Yield:20173-24-4 45%

Reaction Conditions:

with ammonium hydroxide;hydrogen in methanol at 20; under 760.051 Torr;

Steps:

63.1 Step 1: Synthesis of 2-(pyridin-3-yl)ethanamine
A mixture of 2-(pyridin-3-yl)acetonitrile (1 g, 8.47 mmol, 1.00 equiv), Raney nickel (1 g, 17.24 mmol, 1.00 equiv) and ammonium hydroxide (3 mL) in methanol (15 mL) was stirred under 1 atmosphere of hydrogen at room temperature overnight. The catalyst was removed by filtration through a pad of Celite and washed with several portions of methanol. The filtrate and washings were combined and concentrated under vacuum to give 940 mg (45%) of 2-(pyridin-3-yl)ethanamine as a yellow oil. LC-MS: (ES, m/z): 164 [M+CH3CN+H]+, 123 [M+H]+, 106.
