Reaction Steps

The mixture of 4.1 g (7.8 mmol) ethyl (R)-3-(4-amino-3-chloro-5-methyl-phenyl)-2-{[4-(2-oxo-1,2,4,5-tetrahydro-benzo[d][1,3]diazepin-3-yl)-piperidine-1-carbonyl]-amino}-propionate, 60 ml of methanol and 60 ml THF was combined with a solution of 1.5 g (36.8 mmol) lithium hydroxide in 30 ml of water and stirred for 20 hours at 40° C. The reaction mixture was evaporated down under reduced pressure, the residue was taken up in 50 ml of water and acidified by the addition of 2-molar hydrochloric acid solution. The resulting precipitate was suction filtered and dried at 35° C. in the circulating air dryer.
