A solution of benzyl 4-oxopiperidin-1-carboxylate (10 g), β-alanine methyl ester monohydrochloride (5.99 g), acetic acid (4 mL) and sodium triacetoxyborohydride (10.9 g) in dichloroethane (400 mL) was stirred overnight. The reaction mixture was washed with aqueous saturated sodium bicarbonate solution and saturated saline solution, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to obtain the title compound (12.0 g, 87%) as a colorless oil.
