Versuchsvorschrift
In a bomb hydroginator, (S)-methyl 6-(2-(methoxycarbonyl)piperidin-1-yl)-5-nitronicotinate (1.95 g, 6.03 mmol), triphenyl phosphite (0.019 ml, 0.060 mmol), ammonium vanadate (0.056 g, 0.483 mmol) and platinum (5% on carbon, 0.235 g, 0.060 mmol) were mixed in dichloromethane (Volume: 30.2 ml) to give a suspension. The bomb was sealed and pressurized to 110 psi with hydrogen gas. The reaction was stirred at 110 psi 16 h, depressurized, diluted with DCM (100 mL) and refluxed 10 minutes. The hot mixture was filtered through celite and washed with DCM (50 mL). The filtrate was concentrated in vacuo to yield 1.4 g (89%) of the product as a white solid and used without further purification. [M+H] calc'd for C13H15N3O3, 262. found, 262.
