실험 절차

2-(4-Fluorophenyl)-1-(2-cyclopentylamino-4-pyrimidinyl)-5-chloroimidazo[4,5-b]pyridine (50 mg 0.12 mmol), vinyltributylstannane (4.3 ml 0.15 mmol) and PdCl2(PPh3)2 (8.6 mg 0.01 mmol) are dissolved in xylene (1 ml) and heated to 160° C. for 1 h under argon. The reaction mixture is purified over SiO2 (acetone/hexanes 15/85) to yield the title compound as colorless crystals (42 mg 86%)
