To 1,1-dimethylethyl 4-(5-bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-1-piperidinecarboxylate (313 mg, 0.753 mmol) was added ammonium hydroxide (2 mL, 51.4 mmol) and 1,4-Dioxane (1 mL) to a 5 mL microwave vial and heated in microwave for 20 min. at 100° C. After total of 35 minutes the reaction was completed. The reaction was concentrated to give 1,1-dimethylethyl 4-(4-amino-5-bromo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-1-piperidinecarboxylate (336 mg). 1H NMR (400 MHz, DMSO-d6) δ 8.09 (s, 1H), 7.60 (s, 1H), 4.71 (tt, J=5.40, 10.64 Hz, 1H), 4.08 (br. s., 2H), 2.91 (br. s., 2H), 1.81-1.94 (m, 4H), 1.43 (s, 9H).
