A degassed mixture of 4-amino-piperidine-4-carboxylic acid 4-chloro-benzylamide dihydrochloride (48 mg, 0.13 mmol), 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (21 mg, 0.12 mmol), triethylamine (126 uL, 0.9 mmol) and n-butanol (1.2 mL) was stirred at 100° C. for 18 h. The solvents were removed by evaporation and the crude mixture was first purified on a SCX-II acid resin, eluting with methanol then 2M ammonia/methanol, and then by preparative TLC, eluting with 10% methanol in dichloromethane, to give 4-amino-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-piperidine-4-carboxylic acid 4-chloro-benzylamide (37 mg, 0.096 mmol, 80%). LC-MS (LCT2) m/z 385 [M+H+], R, 2.84 min.
