Triethylamine → 2-Chloromethyl-1-nitro-4-phenoxy-benzene

Participants

Reaction Steps

To a round bottom flask equipped with a nitrogen inlet and a water cooled condenser, 2-nitro-5-phenoxy-phenyl-methanol (2.7 g, 11.1 mmol) and triethylamine (4.7 mL, 33.9 mmol) were dissolved in dichloromethane (100 mL). Methane sulfonyl chloride (2.6 mL, 33.3 mmol) was added to the reaction mixture which was subsequently heated to reflux for 16 h. The next day the reaction was removed from the heating source, allowed to cool and poured into a separatory funnel which contained 1N HCl. The organic phase was washed 2 times with 1N HCl and one time with saturated brine solution. The phases were separated and the ethyl acetate layer was dried with sodium sulfate, filtered and the solvent removed under reduced pressure to yield a residue. The residue was purified by flash chromatography using heptanes:ethyl acetate as the mobile phase (9:1) to yield a residue.
