Procedure

A suspension of 1,1-dimethylethyl 5-(4-amino-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-4-fluoro-2,3-dihydro-1H-indole-1-carboxylate (430 mg, 1.121 mmol) and HCl (4 M, dioxane) (10 mL, 329 mmol) was stirred at room temperature overnight. LCMS indicated the reaction was complete, so the reaction mixture was filtered and the residue washed with dioxane (10 mL) and dried at the pump for an hour to afford 5-(4-fluoro-2,3-dihydro-1H-indol-5-yl)-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine 2HCl (314 mg, 79% yield) as an off-white solid. LC-MS (ES) m/z=284 [M+H]+. 1H NMR (600 MHz, DMSO-d6) δ ppm 3.14 (t, J=7.93 Hz, 2H), 3.68 (t, J=7.90 Hz, 2H), 3.84 (s, 3H), 6.83 (br. s., 1H), 7.16 (t, J=6.99 Hz, 1H), 7.59 (s, 1H), 8.49 (s, 1H).
