Procedure

Methanesulfonic acid 2-(3-nitro-phenyl)-ethyl ester was dissolved in piperidine (20 eq) and THF and stirred at 60° C. for one hour. The solvent was removed. The crude product was diluted with ethyl acetate, washed three times with water, dried with anhydrous sodium sulfate, filtered and concentrated. The product was clean enough to carry forward without purification. 44% yield. MH+=235.1.
