A process for preparation of cyclopropylethanol, which comprises subjecting a 3-cyclopropyl-2,3-epoxypropionic acid ester to solvolysis, treating the product of the solvolysis with an acid to obtain cyclopropylacetaldehyde, and reducing the obtained cyclopropylacetaldehyde; and a process for preparation of cyclopropylacetonitrile, which comprises subjecting a 3-cyclopropyl-2,3-epoxypropionic acid ester to solvolysis in the presence of a base, treating the product of the solvolysis with an acid to obtain cyclopropylacetaldehyde, reacting the obtained cyclopropylacetaldehyde with hydroxylamine or salts thereof to obtain cyclopropaneacetaldehyde oxime, and reacting the obtained cyclopropaneacetaldehyde oxime with acetic anhydride. According to the present invention, cyclopropylethanol and cyclopropylacetonitrile can be prepared at low costs and industrially advantageously.
