The compound (18) (62 mg) obtained in item (8) above was dissolved in tetrahydrofuran (3 ml), to which was then added N,N-dimethylchloroforminium chloride (90 mg) under ice-cooling and the resulting mixture was stirred at the same temperature as above for 30 minutes to effect both the chlorination and N,N-dimethylaminomethylenation reactions. Thus, compound (19) was produced.
