Reaction Steps

To a solution of 2-amino-6-fluorobenzamidine dihydrochloride (Example C, 226 mg, 1 mmol) and 4-piperidone ethylene ketal (143 mg, 1 mmol) in dry ethanol (10 ml) was added IN HCl in ether (1 ml, 1 mmol) and the resulting mixture was heated at reflux for 36 h. The solid which separated on cooling was collected by filtration and recrystallised from ethanol to give the title compound (260 mg) as yellow crystals, m.p. 305°-307° C. (dec.).
