Reaction Steps

A solution of (R)-N-(5-bromo-4-(3-(2-(tert-butyldimethylsilyloxy)ethylamino)piperidin-1-yl)-1H-pyrrolo[2,3-b]pyridin-3-yl)-3-chloro-4-fluorobenzamide (30 mg, 0.048 mmol) in THF (2 mL) at room temperature was treated with TBAF (0.048 mL, 0.048 mmol) and stirred for 10 minutes. The mixture was then concentrated in vacuo and purified by reverse phases HPLC (Gilson). The residue obtained was dissolved in a minimal amount of DCM and added to a stirring solution of 1M HCl in ether. The solid formed was filtered, washed with ether and dried to give (R)-N-(5-bromo-4-(3-(2-hydroxyethylamino)piperidin-1-yl)-1H-pyrrolo[2,3-b]pyridin-3-yl)-3-chloro-4-fluorobenzamide hydrochloride (0.015 g, 54% yield). 1H NMR (400 MHz, D2O) δ 8.19 (s, 1H), 7.98-7.94 (m, 1H), 7.82-7.76 (m, 1H), 7.38 (s, 1H), 7.34-7.29 (m, 1H), 3.64-3.61 (m, 2H), 3.42-2.94 (m, 7H), 1.90-1.82 (m, 1H), 1.70-1.62 (m, 1H), 1.44-1.36 (m, 2H); LCMS (APCI+) m/z 510, 512 (M+H)+.
