Participants

Reaction Steps

2-Bromo-1,3-benzothiazole (505.5 mg, 2.36 mmol) and N-(2-aminoethyl) carbamic acid tert-butyl ester (1.1356 g, 7.10 mmol) were stirred in a preheated oil bath (125° C.) for 5 h. The solid mass was dissolved in chloroform, and the resulting solution was washed with aqueous sodium bicarbonate then dried, filtered and concentrated to a yield a residue. The residue was purified by flash chromatography, eluting with 60% ethyl acetate in hexane to yield tert-butyl 2-(benzo[d]thiazol-2-ylamino)ethylcarbamate as a white amorphous solid.
