Into 200 ml of acetic anhydride, 15.4 g of (1-ethyl-2-methylindol-3-yl) (3-carboxypyridin-2-yl) ketone and 13.7 g of 1-n-hexyloxy-3-diethylaminobenzene were added, and the resultant mixture was stirred for 3 hours to 60° to 65° C. After cooling the reaction mixture to room temperature, the cooled reaction mixture was treated by the same manner as in Synthetic Example 1 and as a result, 18.9 of the objective compound of the melting point of 154° to 156° C. as pale blue crystals was obtained. The elementary analytical data of the product were as follows.
