Reaction Steps
The title compound was prepared in substantially the same way was 2,3-dihydro-2-methylthieno[2,3-b]thiophene-2-carboxylic acid-1,1-dioxide. Thus, 2,3-dihydrothieno[2,3-b]thiophene-2-carboxylic acid-1,1-dioxide (10.5 g, 0.048 mol) when reacted with NaH (5.76 g, 60% dispersion in oil) and n-propyl iodide (14 mL, 0.047 mol) in DMF (200 mL) gave the title compound as a gum (11.3 g, 90%).
