After 13 h, MeOH (200 mL) was added and the slurry was filtered over celite. The filter cake was washed with MeOH (600 mL) and the filtrate was concentrated under reduced pressure. The crude material was purified by silica column chromatography (0% to 45% MeOH/EtOAc) to afford tert-butyl (2S,4S)-2-[5-(2- {(2S,5S)-l-[N- (methoxycarbonyl)-L-valyl] -5 -methylpyrrolidin-2-yl} -1,11- dihydroisochromeno[4',3':6,7]naphtho[l,2-d]imidazol-9-yl)-lH-imidazol-2-yl]-4- (methoxymethyl)pyrrolidine-l-carboxylate (4.85 g, 58%). |
