Sodium Hydroxide → 3-(Methanesulfonylmethyl)aniline

Participants

Reaction Steps

Titanium(III)chloride solution (about 15%) in about 10% hydrochloric acid (MERCK (MDA) INCL SCHUCHARDT, 162 ml) was added to a stirred solution of 1-[(methylsulfonyl)methyl]-3-nitrobenzene (5.1 g; 23.8 mmol) in THF (250 ml) at room temperature and the batch was stirred for 16 hours. By adding 1N sodium hydroxide solution the pH value of the reaction mixture was raised to 10 before the batch was extracted with ethyl acetate (2×). The combined organic phases were washed with brine, filtered using a Whatman filter and concentrated to give the desired product (4.5 g) that was used without further purification.
