Methanesulfonyl chloride → 3-(4-Bromophenyl)propyl methanesulphonate

Participants

Reaction Steps

To a stirred solution of 3-(4-Bromophenyl)propan-1-ol (500 g, 2.30 mol) and diisopropylethylamine (312 g, 2.40 mol) in anhydrous dichloromethane (4 L) at 0˜5° C. was added dropwise methanesulphonyl chloride (280 g, 2.40 mol) slowly. After addition, the reaction mixture was stirred for 1 hour at 0˜5° C. The reaction mixture was washed with brine (1 L) twice. The organic phase was concentrated in vacuo to afford the subtitle compound (i) (667 g). HPLC Retention Time=1.353 min.
