NEW MATERIAL:The titled carbamate derivative shown by the formula I (R is naphthalene, group shown by the formula IIWIV).
EXAMPLE: A compound shown by the formula V.
USE: An insecticide for noxious insects effective against various noxious insects, e.g. sanitary noxious insects, agricultural and gardening noxious insects, forest insects, etc., especially having strong effect on bettles which are not controlled with ease.
PREPARATION: For example, a chloroformic ester shown by the formula VI is condensed with an N-methyl-N-propargulamine preferably in a solvent, e.g., an ether, dioxane, etc., to give a compound shown by the formula I. In the reaction, when double equivalent mole of the amine based on the ester is used, an excess amine and hydrochloric acid prepared as a by-product by the reaction form an amine hydrochloride, and preferably the reaction is carried out smoothly.
