Sodium Hydroxide → 4-Chloro-3-cyclopropylmethylthio-2-methylbenzoic acid

Participants

Reaction Steps

3 ml of 20% strength aqueous sodium hydroxide solution were added to 1.20 g (4.43 mmol) of methyl 4-chloro-3-cyclopropylmethylthio-2-methylbenzoate in 30 ml of methanol, and the mixture was stirred at RT for 16 h. For work-up, the mixture was concentrated on a rotary evaporator, and the residue was taken up in water. The mixture was acidified with 1M HCl, and the product was then filtered off as a solid. This gave 1.1 g of pure product.
