(5-Amino-pyridin-3-yl)-{7-[3-(tert-butyl-dimethyl-silanyloxymethyl)-oxetan-3-yl]-7H-pyrrolo[2,3-d]pyrimidin-5-yl}-methanone (Preparation 216, 30 mg, 0.068 mmol) was dissolved in dry pyridine (2 mL) under nitrogen and to this was added (4-chloro-phenyl)-acetic acid (17 mg, 0.102 mmol), followed by HATU (39 mg, 0.102 mmol). The reaction was heated to 50° C. and stirred overnight. The reaction was cooled to room temperature, diluted with dichloromethane and saturated aqueous sodium bicarbonate was added. The phases were separated and the aqueous layer was extracted with dichloromethane (3×5 mL). The combined organics were concentrated to dryness to afford N-(5-{7-[3-(tert-butyl-dimethyl-silanyloxymethyl)-oxetan-3-yl]-7H-pyrrolo[2,3-d]pyrimidine-5-carbonyl}-pyridin-3-yl)-2-(4-chloro-phenyl)-acetamide as a pale yellow solid 35 mg, 87% yield.
