実験手順

Heat 5-(m-methoxyphenyl)-4-methyl-pent-1-yne (8 g), trioxan (0.5 g), 30% formalin (5.5 cc), diethylamine (4 g), acetic acid (2.75 g), dioxan (25 cc) and cuprous chloride (0.12 g) together at 70° for 15 hours. Make cooled solution alkaline with 10% aqueous sodium hydroxide and extract with ether. Wash the ethereal solution with water and extract with 10% hydrochloric acid (3 × 20 cc). Combine the acid extracts, wash with ether and make alkaline with 10% aqueous sodium hydroxide and extract with ether. Wash the ethereal solution, dry, remove the solvent and distil the residue at 0.1 mm to obtain 1-diethylamino-5-methyl-6-(m-methoxyphenyl)-hex-2-yne.
