Procedure

2-Chloro-9-cyclopentyl-5,7,7-trimethyl-8,9-dihydro-5H-pyrimido[4,5-b][1,4]diazepin-6(7H)-one (Intermediate 3) (0.13 g, 0.43 mmol, 1 eq), 4-amino-N-(trans-4-(4-(cyclopropylmethyl)piperazin-1-yl)cyclohexyl)-3-methoxybenzamide (Intermediate 11) (0.26 g, 0.67 mmol, 1.5 eq) and TFA (0.17 mL, 2.2 mmol, 5 eq) in TFE (3 mL) were heated together at 80° C. for 18 hours. Further quantity of Intermediate 6 (0.13 g) was added and the reaction further heated for 48 hours. RM was concentrated in vacuo and the residue was purified by flash column chromatography on silica eluting with 0→20% ammonia/MeOH in DCM gradient followed by preparative HPLC (Preparative 4) then finally preparative RP-HPLC-MS (Preparative 1) to give 4-(9-cyclopentyl-5,7,7-trimethyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-N-((trans)-4-(4-(cyclopropylmethyl)piperazin-1-yl)cyclohexyl)-3-methoxybenzamide (0.03 g, 7%).
