Reaction Steps

(S)-tert-Butyl 1-(4-(6-formylbenzo[d]thiazol-2-yl)piperazin-1-yl)-1-oxo-3-(thiophen-2-yl)propan-2-ylcarbamate (45 mg), cyclopentylamine (12 mg), and sodium triacetoxyborohydride (29 mg) were combined in DCM (1 mL), and the resulting mixture stirred at room temperature overnight, then heated to reflux for 24 hours. The resulting mixture was then cooled to room temperature, quenched with saturated aqueous sodium bicarbonate, extracted with DCM, and chromatographed (0 to 5% MeOH in DCM) to yield (S)-tert-butyl 1-(4-(6-((cyclopentylamino)methyl)benzo[d]thiazol-2-yl)piperazin-1-yl)-1-oxo-3-(thiophen-2-yl)propan-2-ylcarbamate as a colorless oil.
