Participants

Reaction Steps

To a solution of (S)-ethyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(4-(methylamino)-3-nitrophenyl)benzo[d]thiazol-6-yl)acetate (510 mg) in EtOH (4 mL) and EtOAc (2 mL) was added 5% Pt/C (150 mg). The reaction mixture was flushed with hydrogen gas and stirred under hydrogen atmosphere (using a balloon) for 1.5 h. The mixture was filtered through celite and concentrated in vacuo and (S)-ethyl 2-(2-(3-amino-4-(methylamino)phenyl)-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyacetate was used without further purification. LCMS-ESI+: calc'd for C29H33ClN3O3S: 538.2 (M+H+); Found: 538.2 (M+H+).
