実験手順
A solution of 0.13 g (0.29 mmol) of [5-ethynyl-2-(3-hexyl-phenyl)-3-methyl-3H-imidazol-4-yl]-(4-pyrrolidin-1-yl-piperidin-1-yl)-methanone (example 13) in 5 ml of MeOH was treated with 0.031 g (0.03 mmol) of Pd—C (10%) and the reaction mixture was then hydrogenated with H2 (1 bar) at RT for 2 hours. After removal the catalyst by filtration, the solvent was evaporated. The residue was purified by flash column chromatography (CH2Cl2/MeOH 1:0 to 4:1) to give 0.12 g (92%) of the title compound as light yellow oil. MS: 451.1 (MH+).
