Procedure

2′-chloro-9′-cyclopentyl-5′-methyl-8′,9′-dihydrospiro[cyclopropane-1,7′-pyrimido[5,4-b][1,4]diazepin]-6′(5′H)-one (Intermediate 130; 100 mg, 0.32 mmol), 4-amino-2-fluoro-5-methoxy-N-[(3R)-1-methylpyrrolidin-3-yl]benzamide (Intermediate 182; 87 mg, 0.32 mmol) and 4-toluenesulphonic acid monohydrate (154 mg, 0.81 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, washed with methanol and eluted with ammonia in methanol. Product containing fractions were concentrated and purified by base modified reverse phase preparative HPLC to yield the title compound as a white solid (80 mg, 46%).
