32.33 g (200 mmol) of 3-Quinuclidinone hydrochloride was dissolved in 75 ml of water, and to the solution of hydroxylamine hydrochloride (16.4 g; 236 mmol) and CH3CO2Na.3H2O (80 g; 588 mmol) was added. The mixture was stirred at 70° C. for 1 hour. Then NaCl (10 g) was dissolved in the mixture and was cooled to 0° C. Separated crystals were filtered and carefully dried. The obtained crude 3-quinuclidone oxime (approx. 30 g) was used in the next step of the synthesis without further purification.
