Reaction Steps

To a 150 mL round-bottomed flask was added tert-butyl (S)-1-(4-bromo-5-(thiazolo[5,4-c]pyridin-2-yl)thiazol-2-ylamino)-3-(4-(trifluoromethyl)phenyl)propan-2-ylcarbamate (0.157 g, 0.26 mmol), DCM (25.00 mL, 389 mmol) and TFA (5.00 mL, 65 mmol) with a few drops of triethylsilane, and the resulting solution was stirred for about 15 minutes and followed by LCMS. LCMS showed conversion to product so the solvent was removed, and the oil was dissolved in 2 N ammonia in MeOH and adsorbed on to a plug of silica gel. Chromatography through a Redi-Sep® pre-packed silica gel column (12 g), eluting with a gradient of 1% to 10% 2 M ammonia.MeOH in DCM, provided N—((S)-2-amino-3-(4-(trifluoromethyl)phenyl)propyl)-4-bromo-5-(thiazolo[5,4-c]pyridin-2-yl)thiazol-2-amine (0.086 g, 65% yield).
