Participants

Reaction Steps

In a 250 mL round bottom flask was mixed tert-butyl 4-(5-(ethoxycarbonyl)thiophen-2-yl)piperidine-1-carboxylate (5.00 g, 14.73 mmol) in tetrahydrofuran (50 ml). Aqueous 4N NaOH (38.41 ml, 73.6 mmol) solution was added along with some methanol (10 ml) to get a single phase solution. The mixture was stirred overnight at room temperature. The solvents were removed to give a white slurry that was diluted with water and adjusted to pH of 5 with 1N aqueous hydrochloric acid. Filtration provided the title compound.
