Reaction Steps

A solution of [1-(2,4,6-Trimethyl-benzenesulfonyl)-1H-pyrrol-2-yl]-methanol (1.4 g, 5.0 mmol) in CHCl3 (25 ml) was cooled with an ice bath. SOCl2 (1.1 ml, 15 mmol) was added slowly. The solution was allowed to warm to rt, and held an additional 45 min. The solution was then concentrated under reduced pressure. 2-Chloromethyl-1-(2,4,6-trimethyl-benzenesulfonyl)-1H-pyrrole was obtained as a brown solid (1.5 g, 100%). 1H NMR (CDCl3) δ 7.28 (dd, 1H, J=3.3, 1.7 Hz), 6.98 (s, 2H), 6.38-6.34 (m, 1H), 6.19 (t, 1H, J=3.4 Hz), 4.58 (s, 2H), 2.50 (s, 6H), 2.30 (s, 3H).
