Procedure

1.56 g of methyl (E)-4-(4-(N3 -methyl-N2 -cyanoguanidino)phenyl)-3-butenoate was dissolved in 15 ml of dioxane, followed by the addition of 6.9 ml of a 1N aqueous solution of sodium hydroxide. The mixture was reacted at a room temperature for 8 hours. The reaction mixture was concentrated, followed by the addition of water. The obtained aqueous phase was washed with chloroform. The pH of the resulting aqueous phase was adjusted to about 3 by the addition of concentrated hydrochloric acid to precipitate a crystal. This crystal was recovered by filtration and washed with water to obtain 0.84 g of the title compound as a pale yellow powder (yield: 57%).
