Reaction Steps
8.3 parts of 7-diethylamino-3-thiocarbamoylcoumarin and 7 parts of ω-bromo-acetophenone in 30 parts by volume of isopropyl alcohol are boiled with 3 parts of triethylamine for 1 hour. The precipitate is filtered off and washed with isopropyl alcohol and water. 9.1 parts (80.6% of theory) of 7-diethylamino-3-(4-phenylthiazol-2-yl)-coumarin of melting point 127°-130° C. are obtained.
