Reaction Conditions

Reaction Steps

The product B (1.25 g, 3.26 mmol), D (1.37 g, 3.58 mmol), potassium carbonate solution (K2CO3(aq), 2.0 M, 8.0 mL), and dried toluene (24 mL) were charged in a two-necked bottle. The bottle was deoxygenated and purged with nitrogen, and the mixture in the bottle was stirred at 60° C. until it was totally dissolved. The nitrogen pressure of the bottle was increased, and Pd(PPh3)4 (381 mg, 0.33 mmol) was rapidly added into the bottle. The reaction was heated to 110° C., and stirred for 48 hours. The resulting was filtered to remove metal. The filtrate was condensed to remove the solvent. The solid was washed by water and methanol, and then sublimated at a temperature of 260° C. to obtain TSTP (1.50 g, yield=82%) as white solid.
