참여 물질

반응 단계

Paraformaldehyde (5.5 g, 183.33 mmol, 1.60 equiv) and dimethylamine hydrochloride (10 g, 122.70 mmol, 1.00 equiv) were added to a solution of 5-methylhexan-2-one (50 g, 437.83 mmol, 3.00 equiv) and methanol (30 mL). The resulting solution was heated at reflux for about 16 hours, and then the pH was adjusted to about 8 with sodium hydroxide (10%). Standard extractive workup with ether (3×100 mL) gave the title product as a yellow oil (12 g, yield=57%).
