実験手順

A solution of 4-chloro-5-iodo-7-methyl-7H-pyrrolo[2,3-d]pyrimidine (10 mg, 0.034 mmol), 3-biphenyl-boronic acid (7.4 mg, 0.038 mmol), Na2CO3 (36.1 mg, 0.34 mmol) and PdCl2(dppf) (1.4 mg, 0.0017 mmol) in THF (10 mL) was heated to reflux overnight under an argon atmosphere. Reaction was concentrated in vacuo and purified by RP-HPLC (MeCN:H2O:0.1% TFA) to yield ZK103 (3 mg, 28% yield). ESI-MS (M+H)+ m/z calcd 320.1, found 320.0.
