Procedure
5.70 g (20 mmol) N-[2-(4-chloro-2-trifluoromethyl-phenyl)-1,1-dimethyl-ethyl]-formamide and 3.00 g potassium hydroxide are stirred overnight at 140° C. in 20 mL ethyleneglycol. The reaction mixture is combined with water and repeatedly extracted with dichloromethane. The combined organic phases are washed with water, dried with sodium sulphate and evaporated down. The residue is filtered through a short column containing silica gel (eluant: dichloromethane/methanol/ammonia=9:1:0.1).
