Reaction Steps

10-chloro-2-(1-methoxypropan-2-yl)-2,6,9,11-tetrazabicyclo[5.4.0]undeca-7,9,11-trien-5-one (Intermediate 137; 35 mg, 0.13 mmol)), 4-amino-3-methoxy-N-(1-methyl-4-piperidyl)benzamide (WO06/018220; 34 mg, 0.13 mmol) and p-toluenesulphonic acid monohydrate (61 mg, 0.32 mmol) were dissolved in 4-methyl-2-pentanol (2 mL) and heated at 100° C. for 18 hrs. The reaction mixture was cooled to room temperature dissolved in MeOH and added to a 2 g SCX-2 column pre wet with MeOH (2 column volumes). Flushed with MeOH (2 column volumes) and the product eluted with 2M ammonia in MeOH. Product containing fractions were evaporated and the resultant material purified by base modified reverse phase HPLC to yield the title compound as a cream coloured solid (13 mg, 20%)
