Procedure

HCl (4M in dioxane) (0.378 mL, 1.51 mmol) was added to (R)-tert-butyl 4-(1-(4-chlorophenyl)-3-hydroxypropylcarbamoyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate (Intermediate 42) (0.160 g, 0.30 mmol) in DCM (3 mL). The resulting suspension was stirred at 20° C. for 3 hours. The reaction mixture was evaporated. The crude product 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% ammonia) and MeCN as eluents. Fractions containing the desired compound were evaporated to dryness to afford (R)-4-amino-N-(1-(4-chlorophenyl)-3-hydroxypropyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide (0.051 g, 39.3%) as a white solid.
