Reaction Steps

A solution of 25 mg (0.052 mmol) 4-{5-methyl-4-[2-methyl-5-(2,2,2-trifluoro-1-hydroxy-1-trifluoromethyl-ethyl)-indol-1-ylmethyl]-oxazol-2-yl}-phenol (example 99) in 1 mL of pyridine was treated with 28 mg (0.26 mmol) of dimethyl carbamoylchloride and stirred at 60° C. for 2 hours. Et2O and aqueous HCl were added and the phases separated. The aqueous phase was extracted with Et2O and the combined organic phases dried over Na2SO4. Evaporation of the solvent and column chromatography on silica gel with n-heptane/EtOAc 1:1 yielded 19 mg (66%) of dimethyl-carbamic acid 4-{5-methyl-4-[2-methyl-5-(2,2,2-trifluoro-1-hydroxy-1-trifluoromethyl-ethyl)-indol-1-ylmethyl]-oxazol-2-yl}-phenyl ester, light yellow solid, MS: 556 (MH+).
