Versuchsvorschrift

A solution of 4-chloro-5-iodo-7-methyl-7H-pyrrolo[2,3-d]pyrimidine (19 mg, 0.065 mmol), naphthalen-2-yl-2-boronic acid (12.2 mg, 0.071 mmol), Na2CO3 (68.9 mg, 0.65 mmol) and PdCl2(dppf) (26.5 mg, 0.00325 mmol) in THF (3 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 ZK102 (5 mg, 26% yield). ESI-MS (M+H)+ m/z calcd 294.1, found 294.3.
