実験手順

By using 104 ml (3.02 mol) of 40% methylamine aqueous solution instead of n-propylamine, 85 ml of tetrahydrofuran, 9.10 ml (98.8 mmol) of 1,3-dichloropropene (E/Z=9/1), 950 mg (5 mmol) of copper (I) iodide, 355 mg (2 mmol) of palladium chloride, 1.05 g (4 mmol) of triphenylphosphine and 15.0 ml (0.121 mol) of tert-butylacetylene, the treatment was conducted in the same manner as in Example 1 to obtain 12.9 g (yield: 70%) of the above identified compound as off-white crystalline powder.
