Versuchsvorschrift

(R)-2-Amino-2-[6-(4-pentyl-cyclohexyloxy)-naphthalen-2-yl]-propan-1-ol was synthesized as per (R)-2-Amino-2-[6-(cis-4-trifluoromethyl-cyclohexyloxy)-naphthalen-2-yl]-propan-1-ol (Example 259) in 35% yield (and 21% recovered starting material) using (R)-4-Methyl-4-[6-(4-pentyl-cyclohexyloxy)-naphthalen-2-yl]-oxazolidin-2-one as starting material. Note that the starting material contained 20% impurity (mixture of reduced DIAD, reduced DEAD).
