Ethanesulfonylchloride, 2-chloro- → HCID 86702164, compound

Participants

Reaction Steps

To a stirred solution of 2-methylprop-2-en-1-amine (0.500 g, 7.0 mmol), N,N-diisopropylethylamine (3.486 mL, 21.1 mmol) and N,N-4-dimethylaminopyridine (0.043 g, 0.4 mmol) in methylene chloride (20 mL) at 0° C. was slowly added 2-chloroethanesulfonyl chloride (0.734 mL, 7.0 mmol). The reaction mixture was slowly warmed to room temperature and stirred for 16 hrs. The mixture was concentrated and the residue purified by silica gel chromatography (0-80% ethyl acetate/hexanes) to afford the product as a colorless oil (0.59 g, 52%). 1H NMR (300 MHz, CDCl3) δ 6.54 (dd, 1H, J=16.5, 9.6 Hz), 6.27 (d, 1H, J=16.5 Hz), 5.96 (d, 1H, J=9.6 Hz), 4.97 (s, 1H), 4.93 (s, 1H), 4.37 (br s, 1H), 3.60 (d, 2H, J=6.3 Hz), 1.79 (s, 3H).
