Reaction Steps

To a stirred solution of N-[(6-bromopyridin-2-yl)methoxy]-1-(4-methyl-4H-1,2,4-triazol-3-yl)-1-phenylmethanimine (0.125 g, 0.33 mmol, 1 eq.) in 3 ml dry THF “degassed” with N2, was added Cyclopropylacetylene (0.95 g, 0.1 mmol, 3 eq.) followed by N-ethyldiisopropylamine (0.216 g, 1.67 mmol, 5 eq.), Copper Iodide (0.012 g, 0.06 mmol, 0.2 eq.) and Tetrakis(triphenylphosphine)palladium (0.077 g, 0.06 mmol, 0.2 eq.). The reaction was microwaved 120° C./normal/fixed hold/pre stir 100 s for 180 s. The reaction was diluted with EtOAc and filtered through a “celite” plug. The solvent was evaporated and the residue purified by chromatography on silica gel to give N-{[6-(cyclopropylethynyl)pyridin-2-yl]methoxy}-1-(4-methyl-4H-1,2,4-triazol-3-yl)-1-phenylmethanimine (0.068 g, 56% yield) as a yellow viscous oil.
