Participants

Reaction Steps

A solution of 115 mg (4.80 mmol) LiOH in 50 mL water was added to a solution of 1.80 g (3.17 mmol) methyl (S)-2-(3-chloro-4-hydroxy-5-trifluoromethyl-benzyl)-4-oxo-4-[4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidin-1-yl]-butanoate in 50 mL THF and the reaction mixture was stirred overnight at RT. The reaction solution was freed from the THF i.vac., diluted with 150 mL water, the aqueous phase was washed with 150 mL EtOAc, acidified with concentrated HCl, extracted with 150 mL EtOAc, the organic phase was separated off and dried over Na2SO4. After the desiccant and solvent had been eliminated the product was further reacted without purification.
