To a solution of 4-(cyclohexylamino)-1-pent-4-en-1-yl-1,3,8-triazaspiro[4.5]dec-3-en-2-one dihydrochloride (1 g, 2.56 mmol, intermediate I.1.c.1) in DCE (16 mL), was added Hunig's base (0.67 mL, 1.42 mmol), sodium triacetoxyborohydride (0.25 g, 1.18 mmol) and 3-iodo-benzaldehyde (329 mg, 3.83 mmol) in DCE (0.5 mL) dropwise. The reaction mixture was stirred at rt for 18 h, quenched with aq NaHCO3, extracted twice with EtOAc, washed with brine, concentrated in vacuo and purified flash chromatography (silica gel, EtOAc) to provide the desired product LRMS (M+1)=535.
