Participants

Reaction Steps

To a stirred solution of [4-(4-Bromobenzyl)-2-(4-{trifluoromethyl}phenyl)-1,3-thiazol-5-yl]methanol (0.33g, 0.78mmoles, 1eq) in dry 1,2-dimethoxyethane (5ml, 0.16M) was added tetrakis(triphenylphosphino) palladium I (0.45g, 0.39mmoles, 0.5eq) and stirred for 5minutes at room temperature. Phenylboronic acid (0.143g, 1.2mmoles, 1.5eq) was then added followed by the addition of sodium carbonate (2M aqueous solution, 2.3ml, 4.68mmoles, 6eq). The reaction mixture was heated at 100degrees centigrade for 13hours at which point, after cooling to room temperature, the reaction was partitioned between EtOAc and water. After separation of the phases the organic phase washed with brine, dried over anhydrous sodium sulfate, filtered, concentrated in vacuo to yield after purification by silica gel chromatography (CH2Cl2to 2% MeOH/CH2Cl2) 268mg (80%) of product.
