Participants

Reaction Steps

A solution of 3.1 mg (0.13 mmol) LiOH in 1 mL water was added to a solution of 55 mg (0.08 mmol) of (R)-1-(4-amino-3,5-dimethyl-benzyl)-2-(1′-ethoxycarbonylmethyl-4,4′-bipiperidinyl-1-yl)-2-oxo-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate (Example 90) in 5 mL THF and the reaction mixture was stirred overnight at RT. The mixture was evaporated down i.vac., the residue was taken up in 1 mL DMF and the crude product was purified by HPLC. The fractions containing the product were combined and lyophilised.
