Versuchsvorschrift

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; 108 mg, 0.35 mmol) 4-amino-3-chloro-N-(1-ethyl-4-piperidyl)benzamide (Intermediate 212; 118 mg, 0.42 mmol), and p-toluenesulphonic acid monohydrate (133 mg, 0.7 mmol) were combined in 4-methyl-2-pentanol (4 mL) and heated by microwave irradiation at 160° C. for 1 hour. The reaction mixture was loaded onto to an SCX cartridge (10 g) pre-wet with methanol, then washed with methanol and eluted with methanolic ammonia. Product containing fractions were combined and evaporated and the resultant material purified by base modified reverse phase preparative HPLC to yield the title compound as a white solid (38 mg, 20%).
