Reaction Steps

10-chloro-2-cyclopentyl-4,4-dimethyl-2,6,9,11-tetrazabicyclo[5.4.0]undeca-7,9,11-trien-5-one (Intermediate 127; 62 mg, 0.21 mmol) and 4-amino-3-methoxy-N-[(1S,5R)-9-methyl-9-azabicyclo[3.3.1]non-7-yl]benzamide (Intermediate 161; 63 mg, 0.21 mmol) were taken up in 4-methyl-2-pentanol (2 mL) and p-toluenesulphonic acid monohydrate (81 mg, 0.42 mmol) added. The reaction mixture was heated at 160° C. by microwave irradiation for 60 minutes. The cooled reaction mixture was treated with a mixture of methanol & water (5:2 v/v, 7 mL). The resultant solution was loaded onto an SCX-3 cartridge (5 g) pre-wet with methanol. The cartridge was washed through with Methanol (˜40 mL). Products were then eluted with 2M ammonia in methanol (˜30 mL). The ammoniacal solution was evaporated and the resultant material was purified by base modified reverse phase preparative HPLC to yield the title compound as a white solid (64 mg, 54%).
