4-(4,6-Dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride → 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

1.5 g (4.95 mmol) of (2E)-3-{1-[(tert-butoxycarbonyl)amino]-2,3-dihydro-1H-inden-5-yl}acrylic acid and 1.2 g (4.95 mmol) of 2,2,2-trifluoro-1-[3-(trifluoromethyl)phenyl]ethanamine were dissolved in 100 ml of DMF, 1.5 g (5.44 mmol) of 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholin-4-ium chloride were added, and the reaction mixture was heated to 50° C. overnight. The reaction solution was diluted with ethyl acetate, washed with sat. NaHCO3 solution, 1N hydrochloric acid and sat. sodium chloride solution, dried over sodium sulphate, filtered and concentrated. Chromatographic purification gave 2.3 g (4.45 mmol) 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 (87%).
