The reaction mixture was filtered through a pad of Celite® and silica. The solvent was then removed under reduced pressure to give 5.43 g (quantitative yield) of the title compound as off-white crystals: mp 220° C. HRMS m/z calcd for C10H15NO2 (M)+ 181.1103. Found 181.1105. *The corresponding hydrochloride salt has been reported in Bull. Soc. Chim. Fr. 1935, 1737–1741.
