Procedure
A mixture of 2-chloro-5-nitroanisole (0.59 g, 3.1 mmol) and 3-hydroxy pyrrolidine (0.55 g, 6.2 mmol) was heated neat to 110° C. over night. Reaction mass was diluted with ethyl acetate and the organic layer was given water and brine wash, dried over Na2SO4, concentration yields dark red solid (0.6 g, 82% yield). LC-MS, [M+H]+=239.
