HCID 570891944-(4-Trifluoromethylphenylaminosulfonyl)-5-methylisoxazole

Procedure

AA16 was prepared starting from 2-(4-trifluoromethylphenylaminosulfonyl)1-ethoxypropene under the same conditions as described for AA11. Alternatively, AA16 was prepared from 4-trifluoromethylaniline and 4-chlorosulfonyl-5-methylisoxazole.
