N1,N1-dimethyl-N2-((propylimino)methylene)ethane-1,2-diamine (0.70 ml, 3.99 mmol) was added to a stirred solution/suspension of 3-amino-4-bromobenzoic acid (719 mg, 3.33 mmol), (2-(4-methylpiperazin-1-yl)phenyl)methanamine (820 mg, 3.99 mmol) and HOBt (140 mg, 1.0 mmol) in dry DCM (20 ml) under argon. After 24 hrs the reaction mixture was diluted with DCM and washed several times with water. The solvent was removed in vacuo and the resulting yellow oil was triturated with DCM/diethyl to give a yellow crystalline powder;
