A process for the preparation of 1-alkoxy-1-trimethylsilyloxycyclopropanes of general formula (I), wherein R<1> and R<2> are each independently hydrogen or lower alkyl; and R<3> is lower alkyl, by reacting finely divided metallic sodium dispersed in a hydrocarbon with a beta -halogeno carboxylic ester of general formula (II), wherein R<1>, R<2> and R<3> are each as defined above; and X is halogen and chlorotrimethylsilane. According to this process, 1-alkoxy-1-trimethylsilyloxypropanes can be industrially prepared, easily, simply and economically advantageously without any special equipment by using not an ethereal solvent problematic in safety but finely divided metallic sodium dispersed in a hydrocarbon in a yield equivalent to or higher than that attained by using an ethereal solvent.
