To a mixture of 2-(2-ethylaminoindan-5-ylsulfanyl)-2-methylpropionic acid tert-butyl ester and borane complex (11.0 g; 33 mmol), dissolved in CH2Cl2 (100 mL), is added 4-trifluoromethoxyphenyl isocyanate (10.2 g; 50.2 mmol) and the reaction was allowed to stir at RT for 18 h. The solvent was removed under reduced pressure and the crude residue was purified by flash chromatography (SiO2) eluting with a hexanes-EtOAc gradient to afford 11.2 g (62%) of 2-{2-[1-ethyl-3-(4-trifluoromethoxyphenyl)ureido]indan-5-ylsulfanyl}-2-methylpropionic acid tert butyl ester as a white foam.
