Chlorosuccinimide → HCID 66645284, compound

Participants

Reaction Steps

To a solution of (2-bromo-thiazol-5-yl)-ethyl-carbamic acid tert-butyl ester (4.0 g, 13 mmol) in acetonitrile (75 mL) was added N-chlorosuccinimide (3.48 g, 26 mmol) in one portion and the reaction mixture was stirred for 16 h. The reaction mixture was concentrated and the crude product was purified by silica gel chromatography (0 to 100% ethyl acetate/hexanes) to give the desired product as a grey solid (4.2 g, 95%): IR (KBr) 1738 cm−1; 1H NMR (300 MHz, CDCl3) δ 3.61 (q, J=7.1 Hz, 2H), 1.43 (s, 9H), 1.16 (t, J=7.1 Hz, 3H).
