Procedure

1-(1H-Imidazol-1-ylcarbonyl)-4-piperidone ethylene ketal (Example EE, 156 mg., 0.66 mmol) was added to 2-amino-6-fluorobenzamidine dihydrochloride (150 mg, 0.66 is mmol) in ethanol (10 ml) together with an excess of HCl (1M in ether). This mixture was heated to 55° C. overnight, concentrated in vacuo and purified by flash column chromatography eluting with dichloromethane, increasing the gradient to dichloromethane/methanol (10:1), to give a solid which triturated from ethanol/ether to give yellow crystals, m.p. 260° C. (dec.).
