Procedure

A solution of 80 mg (0.11 mmol) of (R)-1-(4-amino-3,5-dimethyl-benzyl)-2-[4-(1-tert-butoxy-carbonyl-piperidin-4-yl)-piperazin-1-yl]-2-oxo-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate (Example 91) in 2 mL of 4 M HCl was stirred overnight at RT. The reaction mixture was made alkaline with solid K2CO3, exhaustively extracted with DCM and the combined organic phases were evaporated down i.vac. Further purification was carried out by HPLC. The fractions containing the product were combined and lyophilised.
