Procedure: A mixture of o-aminoacetophenone (25 g.) and phenylacetic acid (25 g.) in anhydrous methylene dichloride (200 ml.) was prepared. To that mixture was added dicyclohexylcarbodiimide (40 g.) in portions of approx. 10 g. every 5 min. at ambient temperature. When the addition was completed the mixture was stirred for 4 hr. at ambient temperature. The mixture was then filtered, and the filtrate was evaporated in vacuo to dryness. The residue was crystallised from cyclohexane to give o-acetyl-N-(phenylacetyl)aniline, m.p. 78°. was prepared every 5 min. at ambient temperature When the addition at ambient temperature The mixture was then filtered the filtrate was evaporated in vacuo to dryness The residue was crystallised from cyclohexane

Procedure: 2-Acetylaniline (2.0 g) and 2-thenoyl chloride (3.2 g) were condensed in the same manner as in the preparation of compound 95 to obtain N-(2-thenoyl)-2-acetylaniline (3.1 g). The compound (2.0 g) and potassium t-butoxide (9.1 g) were reacted in the same manner as in the preparation of compound 95 to obtain 2-(2-thienyl)-4(1H)-quinolone (compound 100, 310 mg). condensed in the same manner
