Procedure

9-chloro-6-[(3,5-dimethyl-1,2-oxazol-4-yl)methyl]-2-methyl-2,6,8,10-tetrazabicyclo[5.4.0]undeca-7,9,11-trien-3-one (Intermediate 156; 81 mg, 0.25 mmol), 4-amino-3-methoxy-N-(1-methyl-4-piperidyl)benzamide (WO06/018220; 80 mg, 0.30 mmol) p-toluenesulphonic acid monohydrate acid (96 mg, 0.5 mmol) and isopropanol (4 mL) were combined in a 10 mL microwave reactor tube and heated in by microwave irradiation at 150° C. for 80 minutes. The sample was transferred to an SCX (20 g) cartridge pre-wet with methanol, 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 an off white gum (61 mg, 45%).
