実験手順

Hydrogen chloride 4M in dioxane (0.923 mL, 3.69 mmol) was added to (S)-tert-butyl 4-(1-(4-chlorophenyl)-3-hydroxypropylcarbamoyl)-1-(5-cyclopropyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate (Intermediate 65) (420 mg, 0.74 mmol) in dioxane (25 mL). The resulting solution was stirred at ambient temperature for 2 hours. The reaction mixture was dissolved in methanol and purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 3.5N ammonia/MeOH and pure fractions were evaporated to dryness. The product was then purified by preparative LCMS (Waters XBridge Prep C18 OBD column, 5μ 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 (S)-4-amino-N-(1-(4-chlorophenyl)-3-hydroxypropyl)-1-(5-cyclopropyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide (25.0 mg, 7.2%) as a white solid.
