実験手順

A solution of 200 mg (0.4 mmol) of 2-{1-[2-(3-chloro-phenyl)-5-methyl-oxazol-4-ylmethyl]-2-methyl-1H-indol-5-yl}-1,1,1,3,3,3-hexafluoro-propan-2-ol (example 12) in 2 mL of dichloroethane was treated with 0.06 mL (0.8 mmol) of DMF and cooled to 0° C. After addition of 0.04 mL (0.44 mmol) of POCl3 the mixture was allowed to reach RT and stirred for an additional hour. Distribution of the mixture between Et2O and H2O, drying of the combined organic phases over Na2SO4 and column chromatography on silica gel with n-heptane/EtOAc 1:2 yielded 110 mg (52%) of 1-[2-(3-chloro-phenyl)-5-methyl-oxazol-4-ylmethyl]-2-methyl-5-(2,2,2-trifluoro-1-hydroxy-1-trifluoromethyl-ethyl)-1H-indole-3-carbaldehyde, light brown solid, MS: 531 (MH+).
