Versuchsvorschrift

To a solution of material from Example 99 (577 mg, 0.579 mmol) in anhydrous DMF (4 mL) is added piperidine (1 mL, 10.1 mmol). The resulting solution is stirred at room temp for 20 min, then the solvent is removed in vacuo. The resulting solid is evaporated sequentially from ethyl acetate, 1,2-dichloroethane and dichloromethane and dried under high vacuum for several hours to give the title compound as a white solid in quantitative yield that contains 1 equivalent of 1-((9H-fluoren-9-yl)methyl)piperidine as a side product. LC/MS (Condition A): ret. T=4.05 min, (M+H)+ 366.
