Reaction Steps

0.157 g (0.35 mmol) ethyl 2-{[[(2,6-dimethoxybenzyl)amino](imino)methyl]amino}-1,3-thiazole-4-carboxylate bromide were combined with 1.50 ml (17.28 mmol) diisopropylamine and were heated in the microwave at 50 to 70° C. (150 Watt) for 2 hours. In this example, complete reaction was achieved only after further heating in the microwave at 70° C. (150 Watt) by “heating by cooling” after 4.5 hours. The reaction mixture was diluted with 20 ml dichlormethane and was washed with water (3×30 ml). After drying over MgSO4, filtration and removal of the organic solvent under vacuum, the mixture was purified on preparative HPLC (Merck: Chromolith RP-18E, 100-25; eluent water/acetonitrile/0.1 molar acetic acid). 26 mg of 2-{[[(2,6-dimethoxybenzyl)amino](imino)methyl]amino}-N-isopropyl-1,3-thiazole-4-carboxamide were isolated.
