Reaction Steps

4-amino-N-(2-morpholin-4-ylethyl)benzamide (Buttpark; 188 mg, 0.75 mmol) and 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; 160 mg, 0.63 mmol) were heated together in 1:3 EtOH:water (8 ml) in the presence of concentrated hydrochloric acid (126 ul) for 24 hours. The reaction was cooled to ambient temperature and then loaded onto an SCX-2 (5 g) column pre-wet with methanol. The product was eluted with 2M NH3/MeOH and the solvent evaporated to give product as a brown gum. This was purified by reverse phase HPLC to give the title compound a white solid. (125 mg, 42%)
