Procedure

To (6-methoxy-pyridin-3-ylmethyl)-[5-(7H-pyrrolo[2,3-d]pyrimidine-5-carbonyl)-pyridin-2-yl]-carbamic acid tert-butyl ester (73, 66 mg, 0.14 mmol) in 5 mL of dichloromethane, trifluoroacetic acid (0.5 mL, 6.0 mmol) was added. The reaction was stirred at room temperature for 4 hours, then concentrated under vacuum, and combined with aqueous saturated sodium bicarbonate and ethyl acetate. The organic layer was dried over sodium sulfate, filtered and the filtrate adsorbed onto silica. This was purified by silica gel column chromatography eluting with methanol and dichloromethane. Appropriate fractions were combined, the solvents removed under vacuum, and the resulting solid washed with hexanes and ethyl acetate, with sonicating. The solid was collected by filtration to provide the desired compound as a white solid (P-0008, 4.8 mg). MS (ESI) [M+H+]+=360.9.
