Procedure

1.46 g of ethyl acetoimidate hydrochloride was added to a solution of 4-hydroxy-piperidine (1.0 g) in 10 ml of absolute ethanol. The resulting mixture was stirred at room temperature for 6 hours and then allowed to stand for 7 days. After concentration to dryness the obtained oil spontaneously solidified. After crystallization from acetone 0.7 g of the desired product were obtained.
