Reaction Steps
The synthesis was performed starting from ethyl 1-benzyl-7-(2-(cyclopropylmethylsulfonamido)ethoxy)-1,2,3,4-tetrahydronaphthalen-2-ylcarbamate (synthesized in analogy to example 3), which was dissolved in THF (50 ml), after which LiAlH4 was added at room temperature and the mixture was stirred for 8 h under reflux. Addition of 2N aqueous NaOH, extraction with CH2Cl2, washing of the organic layers with saturated NaHCO3 solution and saturated NaCl solution and evaporation of the solvent gave a residue that was treated with iPrOH/HCl after which the product precipitated. After filtration a white salt (287 mg, 58%) were obtained.
