Procedure

p-Toluenesulphonic acid monohydrate (338 mg, 1.78 mmol) was added to 4-amino-2,5-difluoro-N-[(1S,5R)-9-methyl-9-azabicyclo[3.3.1]non-7-yl]benzamide (Intermediate 274; 220 mg, 0.71 mmol), and 2-chloro-9-cyclopentyl-5-methyl-8,9-dihydro-5H-pyrimido[5,4-b][1,4]diazepin-6(7H)-one (Intermediate 1; 200 mg, 0.71 mmol) in 4-methyl-2-pentanol (4 mL) at 25° C. The resulting mixture was heated by microwave irradiation at 150° C. for 1 hour. The crude product was purified by ion exchange chromatography, using an SCX-3 (5 g) column. The desired product was eluted from the column using 2M NH3/MeOH and product-containing fractions were evaporated to dryness. The residue was further purified by base modified reverse phase preparative HPLC to yield the title compound as a white solid (91 mg, 23.%).
