Reaction Steps

(8.1) To a stirring solution of 4-methyl-2-octyloxycarbonylamino-thiophene-3-carboxylic acid ethyl ester (254 mg, 0.74 mmol) in ethanol (2 mL) and THF (2 mL) was added LiOH—H2O (31 mg, 0.74 mmol). The reaction was stirred at RT for 5 days, and then solvent was removed under reduced pressure to give a solid. The product was taken on without further purification: 1H NMR (CDCl3) δ 6.02 (s, 1H), 4.07 (t, 2H, J=6.6 Hz), 2.32 (s, 3H), 1.60-1.40 (m, 2H), 1.27 (bs, 10H), 0.86 (t, 3H, J=6.6 Hz).
