Hydrochloric Acid → 4-(3-Fluoro-piperidin-4-yl)-morpholine

Participants

Reaction Steps

2.0 N HCl in Et2O (15 mL) was added to a solution of 3-Fluoro-4-morpholin-4-yl-piperidine-1-carboxylic acid tert-butyl ester (1.28 g, 4.44 mmol) in DCM (2 mL) and the resulting suspension was stirred at room temperature 4 days. The precipitate was filtered off and tritured with Et2O (2×5 mL) Na2CO3 saturated solution (10 mL) was added and the resulting solution was concentrated under reduced pressure. EtOH (15 mL) was added and precipitate was filtered off.
