実験手順
A solution of 215 mg (0.638 mmol) of 2-[4-amino-3-(4,4-dimethyl-cyclohex-1-enyl)-phenyl]-ethanesulfonic acid dimethylamide (as prepared in the previous step) in CH2Cl2 (10 mL) was treated with 446 mg (0.957 mmol) of PyBroP, 214 mg (0.701 mmol) of 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylate potassium salt (as prepared in Example 1, step (d)) and 333 μL (1.91 mmol) of DIEA and stirred at RT for 18 h. The mixture was diluted with CH2Cl2 (20 mL) and washed with water (1×20 mL). The aqueous layer was extracted with CH2Cl2 (1×20 mL). The combined organic layers were dried (MgSO4) and concentrated in vacuo. Silica gel chromatography of the residue on a 50-g Varian MegaBond Elut SPE column with 25% EtOAc-hexane afforded 355 mg (95%) of the title compound as a white solid: Mass spectrum (ESI, m/z): Calcd. for C29H43N5O4SSi, 586.3 (M+H). found 585.9.
