Hydrochloric Acid → N-(5-Chloropyridin-2-yl)-2-(4-oxopiperidin-1-ylcarbonyl)aminobenzamide

Participants

Reaction Steps

A solution of N-(5-chloropyridin-2-yl)-2-(1,4-dioxa-8-azaspiro[4.5]decan-8-ylcarbonyl)aminobenzamide (120 mg, 0.289 mmol) in dioxane (1 mL) and water (0.25 mL) was treated with 12 N HCl (0.25 mL). After 1.5 h, the mixture was poured into EtOAc and water. The organic layer was washed with satd sodium bicarbonate (2×), brine, dried with sodium sulfate, and concentrated yielding 100 mg of the title compound; which was used without further purification.
