Reaction Steps
In 100 ml of methylene chloride, 21.3 g of 2-amino-4-ethoxycarbonyl-1,3-thiazole was suspended, followed by the addition of 24.8 g of 3,4-dimethoxybenzoyl chloride, 25.3 g of triethylamine and 0.15 g of 4-dimethylaminopyridine. The resulting mixture was refluxed for 2 hours. After the reaction mixture was allowed to cool down, methylene chloride was distilled off under reduced pressure. To the residue, 1000 ml of water was added. Crystals so precipitated were collected by filtration and then recrystallized from ethanol, whereby 30.3 g of the title compound was obtained. Yield: 73%.
