Vorschrift

tert-Butyl 7-(aminomethyl)-1-benzyl-1,2,3,4-tetrahydronaphthalen-2-ylcarbamate (0.600 g, 1.637 mmol) was suspended in dichloromethane (5 mL) and triethylamine (0.228 mL, 1.637 mmol) and cooled to 0° C. Ethanesulfonyl chloride (0.155 mL, 1.64 mmol) was added and the solid gradually dissolved. After 30 minutes the reaction was stopped by washing it with brine (1×50 mL). The organic phase was collected and dried on MgSO4, evaporated. The residue was purified by flash-chromatography on silica gel (100% DCM). Product was obtained as yellow solid (0.653 g, 1.42 mmol, 87%).
