Summary:NEW MATERIAL:The compound of formula (R is lower alkyl). EXAMPLE:4-methoxy-1,3-dioxane-5-carbonitrile. USE:Useful as an intermediate of propenenitrile which is a useful synthetic raw material of vitamin B1. PROCESS:The compound of formula can be prepared by reacting a 3-alkoxy-2- propenenitrile of formula RO-CH=CH-CN with HCHO in the presence of an acid catalyst such as AlCl3 in a solvent such as dioxane, at -20-+300 deg.C under atmospheric pressure of positive pressure for 1-24hr. The amount of formaldehyde is preferably 1-20mol in terms of aldehyde, based on 1mol of the 3-alkoxy- 2-propenenitrile.
