Versuchsvorschrift

2′-Chloro-9′-cyclopentyl-5′-methyl-8′,9′-dihydrospiro[cyclobutane-1,7′-pyrimido[4,5-b][1,4]diazepin]-6′(5′H)-one (Intermediate 4) (0.065 g, 0.2 mmol, 1 eq), 4-amino-N-(trans-4-(4-(cyclopropylmethyl)piperazin-1-yl)cyclohexyl)-3-methoxybenzamide (Intermediate 11) (0.24 g, 0.6 mmol, 3 eq) and TFA (75 μL, 1 mmol, 5 eq) in TFE (6 mL) were heated to reflux together 40 hours. RM was concentrated in vacuo and the residue was partitioned between EtOAc and saturated sodium hydrogen carbonate. The organic layer was separated, washed with saturated brine and concentrated in vacuo to a residue that was purified by preparative RP-HPLC-MS (Preparative—1) to give 4-(9′-cyclopentyl-5′-methyl-6′-oxo-5′,6′,8′,9′-tetrahydrospiro[cyclobutane-1,7′-pyrimido[4,5-b][1,4]diazepine]-2′-ylamino)-N-((trans)-4-(4-(cyclopropylmethyl)piperazin-1-yl)cyclohexyl)-3-methoxybenzamide.
