実験手順

A mixture of 75 mg of 25b, 37 mg of 2-(3,6-dihydro-2H-pyran-4-yl)-4,4,5,5,-tetramethyl-1,3,2-dioxaborolane, 41 mg of K2CO3 and 17 mg of tetrakis(triphenylphosphine)palladium(0) in 3 ml of degassed DMF was heated under N2 atmosphere at 125° C. for 2 hr. The reaction was cooled and diluted with 15 ml of water. The product was extracted with ethyl acetate. The organic extract was washed with water, dried and concentrated. The remainder was chromatographed over silcagel (using a gradient of heptane/acetone as eluent). The product isolated was triturated with diethyl ether, providing 57 mg of white crystalline 25c; Mp 208-210° C. LC-MS-ESI: [M+1] 512.13.
