Abstract
A process for the preparation of an ester of furan of the formula ##STR1## or ##STR2## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each hydrogen or hydrocarbon radicals containing at least one heteroatom comprising subjecting an ester of the formula ##STR3## wherein R.sub.5 is hydrogen or a hydrocarbon radical containing at least one heteroatom to a transesterification reaction with a furan alcohol of the formula ##STR4## in the presence of a catalyst comprising an alkaline carbonate other than lithium carbonate at a temperature of 0.degree. C. to 90.degree. C.
