実験手順

A mixture of 2-(((2S,3R)-1-(2-iodo-5-methylbenzoyl)-3-methylpiperidin-2-yl)methyl)isoindoline-1,3-dione (0.20 g, 0.40 mmol), 2-(tributylstannyl)pyrimidine (0.15 mL, 0.48 mmol), CsF (121 mg, 0.80 mmol), CuI (15 mg, 0.08 mmol) and Pd(PPh3)4 (46 mg, 0.04 mmol) in DMF (10 mL) was degassed and heated at 120° C. for 1 h in a microwave reactor. The solvent was removed in vacuo to obtain the crude which was purified by silica gel chromatography (0˜100% EtOAc/hexanes) to yield the title compound as a brown oil (0.11 g, 61%). MS (ESI) 455 (M+H).
