実験手順

LiAlH4 (1.398 mL, 1.40 mmol) was added dropwise to (R)-methyl 3-(4-(tert-butoxycarbonylamino)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamido)-3-(4-chlorophenyl)propanoate (Intermediate 41) (779 mg, 1.40 mmol) in THF (40 mL) cooled to 0° C. under nitrogen. The resulting solution was stirred at 20° C. for 3 hours. The reaction mixture was quenched with water (1 mL) and neutralised with 2M HCl. The reaction mixture was evaporated to dryness and redissolved in DCM (100 mL) and washed with water (100 mL). The organic layer was dried over MgSO4, filtered and evaporated to afford crude product. The crude product was purified by flash silica chromatography, elution gradient 0 to 10% MeOH in DCM. The pure fractions were combined and evaporated to give (R)-tert-butyl 4-(1-(4-chlorophenyl)-3-hydroxypropylcarbamoyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate (160 mg, 21.63%) as a solid.
