実験手順

A solution of (4-Chloro-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-(3-iodo-phenyl)-methanone (500 mg, 1.1 mmol), Prop-2-ynyl-carbamic acid tert-butyl ester (341 mg, 2.2 mmol), Copper Iodide (21 mg, 0.11 mmol), PdCl2(PPh3)2 (77 mg, 0.11 mmol), and diisopropylamine (111 mg, 1.1 mmol) in THF (25 mL) was stirred at room temperature under N2. After 24 h the reaction was quenched with saturated aqueous NH4Cl and the aqueous layer was extracted with EtOAc (3×). The combined organic layers were dried over Na2SO4 and concentrated. Purification by flash column chromatography (hexanes/ethyl acetate 7:3) afforded the title compound as a yellow solid (452 mg, 86%). %). MS: 479.2/481.2 (MH+); HPLC Rf: 7.26 min. (HPLC method 4).
