2-Aminobenzyl alcohol → N-(2-(hydroxymethyl)phenyl)methanesulfonamide

関与物質

反応手順

A solution of methane sulfonyl chloride (10.2 ml, 0.13 mol) in chloroform (100 mL) was added dropwise to a solution of (2-aminophenyl)methanol (15.0 g, 0.12 mol) in pyridine (100 mL) and chloroform (150 mL) under nitrogen over 1 h at 0° C. The reaction mixture was stirred for 12 h at ambient temperature and then washed with hydrochloric acid (2N, 200 ml×2). The organic phase was dried over anhydrous MgSO4 and concentrated. The residue was purified by flash column chromatography on silica gel (EtOAc/hexane=1:3) to afford N-[2-(hydroxymethyl)phenyl]methanesulfonamide (13.0 g, 53% yield) as a yellow oil.
