Reaction Steps

tert-butyl ((2R,6S,7R,13aS,14aR,16aS,Z)-2-((3-(dimethylamino)-6-methoxyisoquinolin-1-yl)oxy)-7,9-dimethyl-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 (50 mg, 0.062 mmol) was dissolved in DCM (4 mL) and trifluoroacetic acid (TFA, 1 ml, 12.98 mmol) was added. The reaction was stirred for 1 h at room temperature. The volatiles were removed under vacuum to give (2R,6S,7R,13aS,14aR,16aS,Z)-6-amino-2-((3-(dimethylamino)-6-methoxyisoquinolin-1-yl)oxy)-7,9-dimethyl-N-((1-methylcyclopropyl)sulfonyl)-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]diazacyclopentadecine-14a-carboxamide TFA (51 mg) which was used in the next step as is. MS: MS m/z 711.1 (M++1).
