m-Chloroperbenzoic acid → HCID 68586567, compound

Participants

Reaction Steps

0.74 g of the crude product from example 25A is dissolved in 3.4 ml of dry dichloromethane, and 0.74 g (3.21 mmol) of meta-chloroperbenzoic acid is added a little at a time. The reaction mixture is stirred at RT for 8 h, and 2 ml of saturated aqueous sodium bicarbonate solution are then added. With stirring, more sodium bicarbonate powder (about 0.4 g) is added until the evolution of gas has ceased. The aqueous phase is extracted twice with in each case 5 ml of dichloromethane, and the combined organic phases are dried over magnesium sulphate. After removal of the solvent on a rotary evaporator, the crude product that remains is used directly for the subsequent reaction.
