Reaction Steps

A mixture of 120 (20 mmol), acetamidine hydrochloride (40 mmol) and K2CO3 (6.9 g, 50 mmol) in EtOH (50 ml) is heated at 70° C. overnight. The solid is filtered and the residue is dissolved in water (30 ml). Acetic acid is added to adjust the pH to 4. The mixture is then extracted with CH2Cl2 (4×50 ml) and the combined extracts are washed with brine (100 ml). The solution is dried (Na2SO4) and evaporated in vacuo to give a light yellow solid (121), which is used directly in the next step.
