Reaction Steps

A solution of (R)-tert-butyl 1-(5-bromo-3-(3-chloro-4-fluorobenzamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (110 mg, 0.194 mmol) in DCM (3 mL) was treated with TFA (1 mL) at room temperature for 1 hour. The mixture was then concentrated in vacuo. The resulting residue was dissolved in a minimal amount of DCM and added to a stirring solution of 1M HCl in ether. The solid obtained was filtered, washed with ether and dried to provide (R)—N-(4-(3-aminopiperidin-1-yl)-5-bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)-3-chloro-4-fluorobenzamide hydrochloride (80 mg, 76% yield). 1H NMR (400 MHz, D2O) δ 8.22 (s, 1H), 7.97-7.94 (m, 1H), 7.80-7.77 (m, 1H), 7.38 (s, 1H), 7.32-7.28 (m, 1H), 3.54-3.52 (m, 1H), 3.32-3.30 (m, 1H), 3.25-3.21 (m, 1H), 3.18-3.10 (m, 2H), 1.88-1.80 (m, 1H), 1.68-1.63 (m, 1H), 1.50-1.33 (m, 2H); LCMS (APCI+) m/z 466, 486 (M+H)+.
