Procedure

HCl (4M in Dioxane) (3.00 mL, 12.00 mmol) was added to (S)-tert-butyl 4-(1-(4-chlorophenyl)-3-hydroxypropylcarbamoyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate (Intermediate 22) (1.27 g, 2.40 mmol) in dichloromethane (20 mL). The resulting suspension was stirred at 20° C. for 16 hours. The reaction mixture was filtered through a PTFE filtercup and the crude solid was purified by preparative HPLC (Waters XTerra C18 column, 5 μm silica, 19 mm diameter, 100 mm length), using decreasingly polar mixtures of water (containing 1% TFA) and MeCN as eluents. Fractions containing the desired compound were purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7M NH3/MeOH and pure fractions were evaporated to dryness to afford (S)-4-amino-N-(1-(4-chlorophenyl)-3-hydroxypropyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide (0.200 g, 19.4%) as a white solid. 1H NMR (399.9 MHz, DMSO-d6) δ 1.45 (2H, d), 1.86 (1H, d), 1.90-1.93 (1H, m), 2.19 (2H, s), 3.38 (2H, q), 3.51-3.58 (2H, m), 4.35-4.38 (2H, m), 4.53 (1H, t), 4.88 (1H, d), 6.58 (1H, t), 7.16 (1H, t), 7.32-7.38 (4H, m), 8.12 (1H, s), 8.43 (1H, d), 11.63 (1H, s), m/z (ESI+) (M+H)+=429; HPLC tR=1.46 min.
