2.2 g of tert-butyl {5-[(1E)-3-oxo-3-({2,2,2-trifluoro-1-[3-(trifluoromethyl)phenyl]ethyl}-amino)prop-1-en-1-yl]-2,3-dihydro-1H-inden-1-yl}carbamate were dissolved in 40 ml of dioxane and admixed with 10 ml of semisaturated hydrochloric acid, and stirred at room temperature overnight. The reaction mixture was admixed with water and extracted with ethyl acetate. The combined organic phases were dried over sodium sulphate, filtered and concentrated. This gave 1.5 g of (2E)-3-(1-amino-2,3-dihydro-1H-inden-5-yl)-N-{2,2,2-trifluoro-1-[3-(trifluoromethyl)phenyl]-ethyl}-acrylamide (82%).
