実験手順

To (2R,6S,13aS,14aR,16aS)-6-(tert-butoxycarbonylamino)-12,12-difluoro-2-hydroxy-5,16-dioxooctadecahydrocyclopropa[e]pyrrolo[1,2-a][1,4]diazacyclopentadecine-14a-carboxylic acid (Example 7j, 87.4 mg, 0.174 mmol) was added 2-chloro-3-ethylquinoxaline (47.7 mg, 0.247 mmol) and DMF (868 μl). To this solution was added sodium tert-pentoxide (48.9 mg, 0.444 mmol) at room temperature, and the mixture turned dark purple (slightly exothermic). The reaction mixture was stirred at room temperature for 17 h. Additional 2-chloro-3-ethylquinoxaline (18.1 mg, 0.094 mmol) and sodium tert-pentoxide (24.2 mg, 0.202 mmol) were added, and the reaction mixture was stirred for 22 h. The reaction mixture was diluted with CH3CN and neutralized with HCl (1 N, 0.7 ml) and evaporated under reduced pressure. The residue was purified by reverse phase HPLC (CH3CN/H2O (0.1%TFA), gradient=20/80-85/15) to provide the title compound as a light brown solid, (2R,6S,13aS,14aR,16aS)-6-(tert-butoxycarbonylamino)-2-(3-ethylquinoxalin-2-yloxy)-12,12-difluoro-5,16-dioxooctadecahydrocyclopropa[e]pyrrolo[1,2-a][1,4]diazacyclopentadecine-14a-carboxylic acid (66 mg, 57% yield).
