Trifluoroacetic acid (1.0 mL, 0.013 mol) was added to a solution of 1-tert-butyl 3-ethyl 3-[2-(tritylamino)ethyl]piperidine-1,3-dicarboxylate (0.10 g, 0.00018 mol) in methylene chloride (1.0 mL, 0.016 mol) and the mixture was stirred for 1 h at rt to remove the Boc and trityl groups. Then the solvent was removed under vacuum and to the resultant residue was added 1,4-dioxane (3.0 mL, 0.038 mol) followed by N,N-diisopropylethylamine (0.13 mL, 0.00074 mol) and the resultant mixture was stirred at 150° C. (microwave) for 1 h. The solvent from the mixture was removed under vacuum and the crude product was used in the next step without further purification. LC-MS: 155.2 (M+H)+.
