Reaction Steps

The title compound was prepared using the same method as described for Example 42 using 4-(2-bromoethyl)morpholine and (3aR,7S,10S,12R,24aR)-7-tert-butyl-N-[(1R,2S)-2-ethenyl-1-({[1-(methoxymethyl)cyclopropyl]sulfonyl}carbamoyl)cyclopropyl]-19-hydroxy-5,8-dioxo-1,2,3,3a,5,6,7,8,11,12,20,21,22,23,24,24a-hexadecahydro-10H-9,12-methanocyclopenta[18,19][1,10,3,6]dioxadiazacyclononadecino[11,12-b]quinoline-10-carboxamide (Example 35). Purification by flash chromatography (ISCO) afforded the desired product (21.5 mg). LRMS (ES+) m/z 937.3 (M+H)+.
