Reaction Steps
[4-(2-Amino-ethyl)-imidazol-1-yl]-acetic acid methyl ester sulphate (1 g, 3.6 mmol) is suspended in cyclohexanol (50 ml) and treated with concentrated sulphuric acid (5 drops). The reaction mixture is heated to 110° C. for 4 hours and concentrated in vacuo. The residue is dissolved in saturated sodium bicarbonate solution and the mixture is concentrated in vacuo. The resulting solid is triturated with methanol, filtered and the filtrate is reduced in vacuo. The crude solid is dissolved in water, washed with DCM and the aqueous portion is concentrated in vacuo to yield the title product.
