Procedure

5-[(1E)-2-(tert-Butoxycarbonyl)-prop-1-en-1-yl]thiophene-2-carboxylic acid methyl ester (1.18 g, 4.19 mmol) obtained in step 1 was dissolved in tetrahydrofuran (5 mL), 1N aqueous lithium hydroxide solution (4.6 ml) was added, and the mixture was stirred overnight. The mixture was neutralized with 1N hydrochloric acid, and extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated to give the title compound (1.06 g).
