A novel production process of Ixazomib citrate of formula I, wherein the boroester of formula VII is hydrolyzed with boric acid, followed by esterification with citric acid. The hydrolysis with boric acid and esterification with citric acid are performed in a single step. The usual amount of boric acid varies between 1 to 3-fold the amount of the compound of formula VII (molar ratio). In a preferred embodiment the acid is used in a slight excess, i.e. 1.05 to 1.3-fold, optimally 1.1 -fold the molar amount of the compound of formula VII.
