Reaction Steps

Using a method similar to Example 15c), 2.5 g (13.84 mmol) of (1), 2.86 g (16.6 mmol) of naphthylboronic acid and 3.66 g (34.6 mmol) of sodium carbonate were placed in 41 ml of ethylene glycol/8.3 ml of water in the reaction vessel, the mixture was degassed a number of times and saturated with argon. After addition of 1 mg (0.0046 mmol) of palladium acetate and 10.4 mg (0.0184 mmol) of TMSPP, the reaction mixture was stirred for 5 hours at 125° C. The aqueous phase was extracted twice with 50 ml each time of ether, the combined ether phases were washed with 40 ml of water and 40 ml of saturated sodium chloride solution and dried over magnesium sulfate. Removal of the solvent gave 3.08 g of (16) as solid.
