실험 절차

To a stirred solution of N-[(2-bromo-1,3-thiazol-4-yl)methoxy]-1-(1-methyl-1H-tetrazol-5-yl)-1-phenylmethanimine (1 g, 2.63 mmol, 1 eq.) in 20 ml dry THF “degassed” with N2, was added cyclopropylacetylene (70%, 0.996 g, 10.54 mmol, 4 eq.) followed by N-ethyldiisopropylamine (1.36 g, 10.54 mmol, 4 eq.), Copper(I) Iodide (0.025 g, 0.132 mmol, 0.05 eq.) and Tetrakis(triphenylphosphine)palladium (0.152 g, 0.132 mmol, 0.05 eq.). The reaction was stirred for 20 hrs at room temperature for complete conversion. The reaction mixture was diluted with EtOAc (50 ml), filtered through “Chem Elut” cartridge, washed with fresh EtOAc (2×20 ml) and the filtrate was evaporated. The residue was purified by chromatography on silica gel to give N-{[2-(cyclopropylethynyl)-1,3-thiazol-4-yl]methoxy}-1-(1-methyl-1H-tetrazol-5-yl)-1-phenylmethanimine (0.57 g, 60% yield, single stereoisomer) as a brown gum.
