Procedure
4.1 g (10.61 mmol) of (R)-2-amino-3-(3,4-diethyl-phenyl)-1-[4-(4-methyl-piperazin-1-yl)-piperidin-1-yl]-propan-1-one, dissolved in 50 mL of THF, were slowly added dropwise to the ice-cooled mixture of 150 mL of THF and 1.9 g (11.2 mmol) of CDT. Then the mixture was stirred for 30 min in the ice bath and for a further 45 min at RT before the solution of 2.7 g (11.0 mmol) of 3-piperidin-4-yl-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one in 20 mL of DMF was added and the mixture was refluxed for 4 h. The reaction mixture was evaporated down under reduced pressure, the residue was combined with Na2CO3 solution and exhaustively extracted with EtOAc. The combined organic extracts were washed with water, dried over Na2SO4, evaporated down and purified over aluminium oxide. The product was obtained as a solid.
