Reaction Steps

A suspension of 2-(4-bromonaphthalene-2-yl)-4-methylthiazole-5-carboxylic acid ethyl ester (0.050 g), zinc cyanide (0.031 g) and tetrakis(triphenylphosphine)palladium (0.015 g) in N-methylpyrrolidone (2 mL) was stirred at 150° C. for 50 minutes using microwave reactor (Biotage). To the reaction mixture was added water (15 mL), and the precipitated solid was collected by filtration, and washed with water and n-hexane to give 2-(4-cyanonaphthalene-2-yl)-4-methylthiazole-5-carboxylic acid ethyl ester (0.042 g).
