[0191] Methyl 1-bromonaphthalene-2-carboxylate (70.0g, 264mmol), phenylboronic acid (38.6g, 317mmol) and potassium phosphate monohydrate (182g, 792mmol) were dissolved in 0.2l toluene, 0.2l di Alkane and 0.21 water, and palladium acetate (1.18 g, 5.3 mmol) and tri-o-tolylphosphine (3.2 g, 10.6 mmol) were added. The batch was heated at reflux overnight, cooled to room temperature and expanded with distilled water. After phase separation, the aqueous phase was extracted several times with toluene. The combined organic phases were washed with distilled water, dried over magnesium sulfate and filtered through aluminum oxide. The organic phase was evaporated to give an orange oil, yielding 69 g of product (99% of theory).
