関与物質

反応手順

A solution of 2-di-n-propylamino-8-acetyl-1,2,3,4-tetrahydronaphthalene (0.3 g, 1.1 mmol), prepared as in Example 5, and tris(dimethylamino)methane (0.32 g, 2.2 mmol) in toluene was heated to reflux for 5 hours and at 60° for 18 hours. An additional aliquot of tris(dimethylamino)methane (0.16 g, 1.1. mmol) was added and the reaction stirred at 60° for an additional 2 hours. The reaction was concentrated to give 2-di-n-propylamino-8-(1-oxo-3-(dimethylamino)-prop-2-enyl)-1,2,3,4-tetrahydronaphthalene (0.39 g) as a viscous, orange oil.
