5-(4-chloro-phenyl)-N-((1R,2R)-2-hydroxy-cyclohexyl)-6-(3-methoxy-prop-1-ynyl)-nicotinamide → 5-(4-Chloro-phenyl)-N-((1R,2R)-2-hydroxy-cyclohexyl)-6-(3-methoxy-propyl)-nicotinamide

Reaction Steps

Palladium on charcoal (18 mg, 10%) was added to a solution of 5-(4-chloro-phenyl)-N-((1R,2R)-2-hydroxy-cyclohexyl)-6-(3-methoxy-prop-1-ynyl)-nicotinamide (100 mg, 0.25 mmol) in ethylacetate (12 mL). The mixture was hydrogenated for 2 h at room temperature and 0.4 bar positive hydrogen pressure after which the theoretical amount of hydrogen had been consumed. The catalyst was then filtered off and the solvent was evaporated to afford 5-(4-Chloro-phenyl)-N-((1R,2R)-2-hydroxy-cyclohexyl)-6-(3-methoxy-propyl)-nicotinamide without further purification as a orange solid 93 mg (92% yield). m/z (ISP+): 403.2, 405.2 (M+H).
