Reaction Steps

A solution of tert-butyl((2R,6S,7R,13aS,14aR,16aS,Z)-7-ethyl-2-hydroxy-9-methyl-14a-(((1-methylcyclopropyl)sulfonyl)carbamoyl)-5,16-dioxo-1,2,3,5,6,7,8,9,10,11,13a,14,14a,15,16,16a-hexadecahydrocyclopropa[e]pyrrolo[1,2-a][1,4]diazacyclopentadecin-6-yl)carbamate (0.062 g, 0.1 mmol) and CDI (0.019 g, 0.120 mmol) was stirred for 6 h. To the solution was added 4-fluoroisoindoline (0.018 g, 0.130 mmol), and then stirred overnight. Concentration gave 80 mg of a crude mixtures (2R,6S,7R,13aS,14aR,16aS,Z)-6-((tert-butoxycarbonyl)amino)-7-ethyl-9-methyl-14a-(((1-methylcyclopropyl)sulfonyl)carbamoyl)-5,16-dioxo-1,2,3,5,6,7,8,9,10,11,13a,14,14a,15,16,16a-hexadecahydrocyclopropa[e]pyrrolo[1,2-a][1,4]diazacyclopentadecin-2-yl 4-fluoroisoindoline-2-carboxylate, which was used as it was.
