1 is a substituted or unsubstituted lower-alkyl or phenyl group; and R
2 is a substituted or unsubstituted lower alkyl or alkenyl group) and an aldehyde of formula (4) (wherein R
3 is hydrogen, a substituted or unsubstituted lower alkyl group, or a substituted or unsubstituted phenyl group) by contact with a basic catalyst in the presence of an additive selected from among 2 to 12C compounds containing a hydroxy group and/or an amino group.
