Procedure
2′-chloro-9′-cyclopentyl-5′-methyl-8′,9′-dihydrospiro[cyclohexane-1,7′-pyrimido[5,4-b][1,4]diazepin]-6′(5′H)-one (Intermediate 255; 80 mg, 0.24 mmol), 4-amino-3-methoxy-N-(1-methyl-4-piperidyl)benzamide (WO06/018220; 63 mg, 0.24 mmol) and p-toluenesulphonic acid monohydrate (114 mg, 0.60 mmol) were heated in 4-methyl-2-pentanol (3 mL) at 140° C. for 3 hours. The mixture was cooled and absorbed on to an SCX column, which was then washed with methanol and eluted with ammonia in methanol. Product containing fractions were evaporated and the residue purified on a silica column (2% 7N ammonia in methanol/DCM) to give the title compound as a white solid. (70 mg, 52%)
