Versuchsvorschrift

A solution of 132 mg (0.377 mmol) of 2-cyclohex-1-enyl-4-[2-(mopholine-4-sulfonyl)-ethyl]-phenylamine (as prepared in the previous step) in CH2Cl2 (15 mL) was treated with 126 mg (0.414 mmol) of 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylate potassium salt (as prepared in Example 1, step (d)), and 93.9 mg (0.565 mmol) of PyBroP to form a slurry, which was treated with 197 μL (1.13 mmol) of DIEA. The mixture was stirred at RT for 3.5 h, diluted with CH2Cl2 (15 mL), and washed with saturated aqueous NaHCO3 (1×20 mL). The organic layer was dried (MgSO4) and concentrated in vacuo to afford 221 mg (98%) of the title compound as an off-white solid: Mass spectrum (ESI, m/z): Calcd. for C29H41N5O5SSi, 600.3 (M+H). found 599.8.
