실험 절차

The starting material, thieno[3,4-b][1,5]benzoxazepin-10(9H)-one (I) or 7-methyl-thieno[3,4-b][1,5]benzoxazepin-10(9H)-one (II) in ethanol is treated with sodium methoxide and methyl iodide and extracted with methylene chloride to yield 9-methyl-thieno[3,4-b][1,5]benzoxazepin-10(9H)-one (III) and 7,9-dimethyl-thieno[3,4][1,5]benzoxazepin-10(9H)-one (IV) respectively. The above compounds III and IV are refluxed with 5 N sodium hydroxide for 16 hours, diluted with water, adjusted to pH 4-5 with hydrochloric acid and extracted with methylene chloride. The base compounds thus obtained are dissolved in ether and treated with alcoholic hydrochloric acid to give the corresponding 4-(o-methylaminophenoxy)-3-thiophenecarboxylic acid hydrochloride (V) and 4-(2-methylamino-p-tolyloxy)-3-thiophenecarboxylic acid hydrochloride (VI) compounds.
