37% Formaldehyde (11.7 mL) was added to a slurry of benzyloxyamine hydrochloride (25.0 g, 0.156 mole) in 50 mL H2O. NaOH (6.3 g) in 25 mL H2O was then added over 20 minutes. The temperature rose to 40°. After stirring 2 hours, the reaction mixture was extracted 1×100 mL and 2×25 mL of ether. The ether extracts were combined, washed 2×50 mL saturated NaHCO3 and then 2×50 mL brine, dried and evaporated to yield title product as an oil, 20.0 g b.p. 195.5°.
