実験手順

To a 10 mL vial was added trans-cyclohexane diamine (13.4 mg, 0.12 mmol, 1.0 equiv), 3-bromo-5-(3,3-dimethyl-but-1-ynyl)-thiophene-2-carboxylic acid methyl ester (70.8 mg, 0.24 mmol, 2.0 equiv), K2CO3 (32.5 mg, 0.24 mmol, 2.0 equiv), CuI (22 mg, 0.12 mmol, 1.0 equiv), (R)-5-cyclohexyl-2-(3-hydroxy-propyl)-2-methyl-morpholin-3-one (30 mg, 0.12 mmol, 1.0 equiv) and 1,4-dioxane (0.4 mL). The mixture was flushed with N2 and stirred at 120° C. for 18 hours. The mixture was filtered through celite and the filtrate was concentrated under vacuum. The residue was purified by silica gel column chromatography, EtOAc/heptane 80% to give product 15 mg (yield 26%).
