実験手順

[5-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-9H-thioxanthen-2-yl]-carbamic acid tert-butyl ester (1.12 g), 2-chloro-6-morpholin-4-yl-pyran-4-one (0.66 g, 3.06 mmol) and grinded K2CO3 (0.71 g, 5.10 mmol) were dissolved in dry 1,4-dioxane (5 ml). The mixture was degassed for 15 mins and Pd(PPh3)4 (0.15 g, 0.13 mmol) was then added The dark brown mixture was heated to 100° C. under an atmosphere of N2 for 24 hour. The reaction mixture was concentrated in vacuo and water (50 ml) was added. The brown solid was filtered, washed with water, dried overnight in a vacuum desiccator and was used without any further purification (1.51 g). m/z (LC-MS, ESP), RT=4.47 min, (M++1)=493
