실험 절차

A solution of 365 mg (1.18 mmol) of 2-(4-amino-3-cyclohex-1-enyl-phenyl)-ethanesulfonic acid dimethylamide (as prepared in the previous step) in CH2Cl2 (10 mL) was treated with 827 mg (1.78 mmol) of PyBroP, 398 mg (1.30 mmol) of 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylate potassium salt (as prepared in Example 1, step (d)), and 618 μL, (3.55 mmol) of DIEA at RT for 16.5 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) and the combined organic layers dried (MgSO4) and concentrated in vacuo. Silica gel chromatography of the residue on a 50-g Varian MegaBond Elut SPE column with 25-40% EtOAc-hexane afforded 660 mg (100%) of the title compound as a white solid: Mass spectrum (ESI, m/z): Calcd. for C27H39N5O4SSi, 558.2 (M+H). found 557.9.
