実験手順
Hydroxyethyltriethylammonium bromide was obtained as follows: ##STR14## Bromoethanol (distilled, 2 g, 16 mmole) and triethylamine (1.62 g, 16 mmole) were heated in dichloromethane (30 ml) at 40° C. for 16 hours. After cooling the precipitate was filtered and dried over phosphorus pentoxide to yield hydroxyethyltriethylammonium bromide as a white powder, 1.47 g, 6.5 mmole, 41% yield.
