실험 절차

N-((7-Amino-8-benzyl-5,6,7,8-tetrahydronaphthalen-2-yl)methyl)ethanesulfonamide (0.243 g, 0.678 mmol) and 3-oxetanone (0.098 g, 1.356 mmol) were sealed in a vial and heated at 210° C. for 2 minutes. Trimethylsilyl cyanide (0.181 mL, 1.356 mmol) was added, the vial was resealed and the mixture was heated again at 210° C. for 2 minutes. The mixture was diluted with ethyl acetate (40 mL) and washed with 1 N NaOH (1×20 mL) and brine (1×20 mL). The organic extract was collected, dried on MgSO4 and evaporated under reduced pressure to give a brown oil. The residue was purified by preparative HPLC. Product was obtained as a colourless oil (7.2 mg, 0.016 mmol, 2.4%).
