Reaction Steps

Dilute tert-butyl 1-((4-(2-(2-(2-(1H-1,2,3-triazol-1-yl)ethylamino)-5-fluoropyrimidin-4-yl)benzo[b]thiophen-7-yl)-6-fluoropyridin-3-yl)methyl)pyrrolidin-3-yl(methyl)carbamate (118 mg, 0.18 mmol) in DCM (3 mL) and treat with 4 M hydrochloric acid in dioxane (0.45 mL, 1.8 mmol). Heat the mixture at 35° C. for 2 h. Remove the organic solvent to give the crude deprotected product. Dilute in DCM (3 mL) and methanol. Pour the mixture onto a strong cation exchange (SCX) (10 g) column. Elute the desired product with 2 N methanolic ammonia (40 mL) and concentrate. Dry the concentrated material from 1:1 acetonitrile/water by lyophilizing to afford the title compound (88 mg, 46%). MS (ES) m/z 548 [M+1]+.
