The reaction mixture was placed under a hydrogen atmosphere at 1 atmosphere for 21 hours. Subsequently, additional Pearlman catalyst (0.2 g) was added and the reaction continued to be stirred for 5 hours under a hydrogen atmosphere to achieve dechlorination. Upon completion of the reaction, the mixture was filtered through a diatomaceous earth pad and the filtrate was concentrated. Purification by column chromatography (eluent ratio 5:95 methanol:dichloromethane) afforded (2-methylpyridin-4-yl)methanol (1.48 g, 88% yield). The obtained (2-methylpyridin-4-yl)methanol can be used to prepare 2-amino-3-(2-methylpyridin-4-yl)propionitrile, and 1-methyl-1H-indol-2-one carboxylic acid ((1S,2R)-2-{[cyano -(2-methylpyridin-4-ylmethyl)-methyl]-carbamoyl}-cyclohexyl)amide obtained by the method described above (186 mg, yield 62%). Results of mass spectrometry analysis: m/z 444 (M+H). | | References | [1] Patent: US2004/77646, 2004, A1. Location in patent: Page 116 |
