Versuchsvorschrift

tert-Butyl 1-benzyl-7-((cyclopropylmethylsulfonamido)methyl)-1,2,3,4-tetrahydronaphthalen-2-ylcarbamate (0.602 g, 1.242 mmol) was dissolved in dichloromethane (5 mL) and trifluoroacetic acid (0.5 mL, 6.49 mmol) and stirred overnight at room temperature. The solution was evaporated and partitioned between saturated aqueous NaHCO3 and ethyl acetate. Water was extracted with ethyl acetate (2×30 mL). The collected organic extracts were dried on MgSO4 and evaporated under reduced pressure to give a brown oil. Product was obtained as a brown oil (0.470 g, 1.22, 98%).
