PURPOSE: To obtain the titled compound useful as a synthetic intermediate for pharmaceuticals, etc., in high yield at a low production cost without accompanying side reactions, by reacting an olefin with a formic acid derivative in carbon monoxide atmosphere in the presence of a catalyst containing a platinum group metal complex.

CONSTITUTION: An olefin which is an unsaturated hydrocarbon having carbon- carbon double bond (e.g. cyclohexene) is made to react with a formic acid derivative (e.g. formic acid amide, formic acid ester, etc.) in carbon monoxide atmosphere in the presence of a catalyst containing a platinum group metal complex free from halogen [e.g. Ru3(CO)12] at 150W300°C under 1W200kg/cm2 pressure for 10W48hr. The molar ratio of the olefin to the formic acid derivative is 2W100 and the concentration of the catalyst is 0.01W10mol% based on the formic acid derivative.
