実験手順

100 mg of compound 88, 118 mg of Boc-(4-hydroxy)piperidine and 416 mg of Diphenyl-[4-[1H,1H,2H,2H-perfluorodecyl]phenyl]phosphine were dissolved in 5 mL of dry tetrahydrofuran. 208 mg of Bis (1H, 2H, 2H, 3H, 3H-perfluorononyl)-azodicarboxylate were added and the reaction was allowed to stir overnight. The mixture was evaporated to dryness and filtered over a 5 g Fluoro-Flash cartridge. The obtained crude product was purified by preparative HPLC to yield 46 mg of the desired product.
