To a solution of (S)-tert-butyl-4-(3-(6-(methylsulfonyl)pyridine-3-yloxy)-2-oxopyrrolidin-1-yl)piperidine-1-carboxylate (259 mg, 0.59 mmol) in DCM (10 mL) was added excess 4N HCl in dioxane (3 mL). The reaction was stirred for 4 hours, then concentrated in vacuo to yield (S)-3-(6-(methylsulfonyl)pyridin-3-yloxy)-1-(piperidin-4-yl)pyrrolidin-2-one hydrochloride salt (210 mg, 94%) as an off white solid, which was used without any further purification.
