Reaction Steps

Into 150 ml of acetic anhydride, 14.7 g of (1,2-dimethylindol-3-yl) (3-carboxypyridin-2-yl) ketone and 13.3 g of 1-cyclohexyloxy-3-diethylaminobenzene were added and the resultant mixture was stirred for 3 hours at 60° to 65° C. After cooling the reaction mixture to room temperature, the cooled mixture was treated by the same procedures as in Synthetic Example 7 and 19.7 g of the object compound was obtained as pale blue crystals (melting point: 161° to 165° C.).
