10-chloro-6-methyl-2-(1-methyl-4-piperidyl)-2,6,9,11-tetrazabicyclo[5.4.0]undeca-7,9,11-trien-5-one (Intermediate 118; 39 mg, 0.13 mmol), 4-amino-N-cyclohexyl-3-methoxy-benzamide (Intermediate 119; 31 mg, 0.13 mmol) and p-toluenesulphonic acid monohydrate (60 mg, 0.31 mmol) were combined in 4-Methyl-2-pentanol (2 mL) and heated at 100° C. for 16 hrs. The reaction mixture was cooled to room temperature and dissolved in Methanol and added to a 5 g SCX-3 column pre wet with MeOH (2 column volumes). Flushed with MeOH (2 column volumes) then crude product eluted with 2M ammonia in MeOH and solvents evaporated. The resultant material was dissolved in DCM and purified on silica eluting with a shallow (25 column volumes) gradient of 0-10% MeOH/DCM. Product containing fractions were combined and evaporated to a yellow gum which was purified by base modified reverse phase HPLC to give the title compound as a white solid. (15 mg, 23%).
