10-chloro-6-methyl-2-propan-2-yl-2,6,9,11-tetrazabicyclo[5.4.0]undeca-7,9,11-trien-5-one (Intermediate 76; 150 mg, 0.59 mmol), 4-amino-3-chloro-N-(2-morpholin-4-ylethyl)benzamide (Intermediate 52; 168 mg, 0.59 mmol), and p-toluenesulphonic acid monohydrate (281 mg, 1.47 mmol) were heated in 4-methyl-2-pentanol (4 mL) at 140° C. for 2 hours. The reaction mixture was cooled and loaded onto an SCX-3 column pre-wet with Methanol. The column was washed with methanol to remove p-toluenesulphonic acid monohydrate and then washed with 2% 7N ammonia/methanol to elute the crude product. Product containing fractions were evaporated and the resultant material purified by reverse phase HPLC to yield the title compound as an orange gum (46 mg, 15.6%).
