This compound can be obtained by two different ways: 1) The condensation of 2-mercapto-6-ethoxybenzothiazole (I) with 2-bromo-2-phenylpropionate (II) by means of sodium ethoxide in refluxing ethanol gives 2-phenyl-2-[(6-ethoxy-2-benzothiazoyl)thio]propionate (III), which is then hydrolyzed with KOH in ethanol. 2) By condensation of 2-chloro-6-ethoxybenzothiazole (IV) with 2-mercapto-2-phenylpropionic acid (V) by means of NaOH in refluxing butanol.
