Versuchsvorschrift
2-Acetylfuran (13.8 g), dimethylamine hydrochloride (13.3 g), paraformaldehyde (5.0 g) and ethanol (80 ml) acidified with concentrated HCl (1.0 ml) were stirred. Part of this mixture (27 ml) was pumped through the CMR (18 ml/min; 160°-70° C.; 500 kPa;) and the hot product collected in an ice-water cooled flask, to afford pale yellow crystals m.p. 172.5°-173° C. (cf lit.10 m.p. 173°-4° C.) in 13% yield.
