Participants

Reaction Steps

To a 1 mL DMF solution of 6-(7-cyclohexyl-6-dimethylcarbamoyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)-nicotinic acid (50 mg, 0.122 mmol) was added DIPEA (32 mg, 0.043 mmol) and HBTU (49 mg, 0.129 mmol). After stirring for 15 m at room temperature 3,8-diaza-bicyclo[3.2.1]octane-8-carboxylic acid tert-butyl ester (31.2 mg, 0.147 mmol) was added and the reaction mixture was left to stir at room temperature for 4 h. The reaction was quenched by pouring into brine and extracted with EtOAc. The organic extracts were dried with Na2SO4, filtered and concentrated. The crude product was purified by NP-LC (Analogix, 10% MeOH in EtOAc) to yield 3-[6-(7-cyclohexyl-6-dimethylcarbamoyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)-pyridine-3-carbonyl]-3,8-diaza-bicyclo[3.2.1]octane-8-carboxylic acid tert-butyl ester (60 mg, 0.10 mmol). MS m/z 603.5 (M+H)+.
