10-chloro-4,4-diethyl-6-methyl-2-propan-2-yl-2,6,9,11-tetrazabicyclo[5.4.0]undeca-7,9,11-trien-5-one (Intermediate 198; 100 mg, 0.322 mmol), p-toluene sulphonic acid monohydrate (153 mg, 0.81 mmol) and 4-amino-3-methoxy-N-(1-methyl-4-piperidyl)benzamide (WO06/018220; 84 mg, 0.322 mmol) were added to 4-methyl-2-pentanol (7 mL). The reaction was heated at 120° C. over the weekend. The reaction mixture was loaded on to an SCX column (10 g), pre-wet with methanol, washed with methanol and eluted with ammonia in methanol. Product containing fractions were combined and evaporated and the resultant material purified by base modified reverse phase preparative HPLC to yield the title compound, after drying under vacuum at 70° C., as a white solid (97 mg, 56%)
