Reaction Steps

A solution of N-[(2-bromo-1,3-thiazol-4-yl)methoxy]-1-(1-methyl-1H-tetrazol-5-yl)-1-phenyl-methanimine (190 mg, 0.50 mmol), benzyl propargyl ether (149 mg, 1.00 mmol), copper(I) iodide (9.5 mg, 0.05 mmol), tetrakis(triphenylphosphine)palladium(0) (28.9 mg, 0.02 mmol), N,N-diisopropylethylamine (258 mg, 2.0 mmol) in degassed tetrahydrofuran (2.5 mL) was stirred under an Argon atmosphere at 50° C. for 14 h. After the addition of diethylether (2 mL) the suspension was filtered over a pad of silica gel and the filtrate was concentrated in vacuo. Purification on silica gel afforded N-({2-[3-(benzyloxy)prop-1-yn-1-yl]-1,3-thiazol-4-yl}methoxy)-1-(1-methyl-1H-tetrazol-5-yl)-1-phenylmethanimine as a thick oil (144 mg, yield 62%).
