실험 절차

To a solution of 2-({2-[(4-nitrophenyl)oxy]ethyl}oxy)tetrahydro-2H-pyran (Intermediate 17) (1.33 g, 5 mmol) in EtOH (50 mL) was added Pd/C (catalytic amount) and ammonium formiate (0.9 g, 10 eq). The reaction was stirred to 40° C. for 2 hours. After filtration on celite, the solvent was evaporated and the residue was poured in water, extracted with ether and dried over sodium sulphate and evaporated. The title compound was obtained as a dark oil (0.8 g, 68%). LC/MS: m/z 238 (M+H)+, Rt: 2.38 min.
