The present invention provides a method for producing a 3-cyanopyrrole compound that is useful as an intermediate for pharmaceutical products. A method for producing a compound (II), which comprises subjecting a compound (I) to a reduction reaction, and wherein the reduction reaction is a continuous hydrogenation reaction carried out in a fixed-bed reactor that is filled with a metal supporting catalyst. A method for producing a compound (III), which comprises subjecting the compound (I) to a ring-forming reaction after the reduction reaction, and wherein the reduction reaction is a continuoushydrogenation reaction carried out in a fixed-bed reactor that is filled with a metal supporting catalyst.
