실험 절차

To a slurry of 4-cyano-1H-imidazole-2-carboxylic acid (2-cyclohex-1-enyl-4-piperidin-4-yl-phenyl)-amide trifluoroacetic acid salt (81 mg, 0.16 mmol, as prepared in Example 14, step (b)) in CH2Cl2 (3 mL) was added NEt3 (33 μL, 0.24 mmol). The solution was then treated with 2,2-dimethyl-[1,3]dioxan-5-one (31 mg, 0.24 mmol) and the reaction was allowed to stir for 3 h. At this time NaBH(OAc)3 (51 mg, 0.24 mmol) was added in one portion, and the reaction was allowed to stir for an additional 4 h. The reaction was diluted with H2O (10 mL) and extracted with EtOAc (2×25 mL). The organic extracts were dried (Na2SO4) and concentrated in vacuo. Purification by silica gel preparative thin layer chromatography (10% MeOH—CHCl3) afforded 22 mg (28%) of the title compound as an off-white semi-solid. Mass spectrum (ESI, m/z): Calcd. for C28H35N5O3, 490.2 (M+H). found 490.6.
