Participants

Reaction Steps

3.2 g of ethyl 2-[4-(tert-butoxycarbonylamino)-3-(2-isoindolin-2-yl-2-oxoacetyl)phenyl]-2-methylpropanoate are dissolved in 100 ml of acetonitrile under argon. 1.012 g of caesium fluoride and 1.81 ml of bis(trimethylsilyl)carbodiimide are added to the solution. The mixture is stirred at room temperature for 15 min, and 14 ml of hydrochloric acid (1N) are then added, and the mixture is neutralised using bicarbonate. The aqueous phase is washed three times with 100 ml of ethyl acetate each time. The combined organic phases are dried over sodium sulfate, filtered and evaporated to dryness in vacuo.
