Procedure

A solution of (E)-tert-butyl 4-(3,3-difluoroprop-1-enyl)-4-hydroxypiperidine-1-carboxylate (38C) (293 mg, 1.075 mmol) in 5 mL of 3.5 N HCl in dioxane was stirred at r.t. for 30 min. The reaction mixture was concentrated in vacuo to give 300 mg of the title product as a yellow liquid which was used in the next step directly.
