Procedure

A mixture of 1-(4-benzyloxy-2,6-dimethylphenyl)-3-amidinourea hydrochloride (7.0 g), methanolic HCl (50 ml), 5% Pd/C (1.0 g) and 150 ml of absolute ethanol are shaken under an atmosphere of H2 (50 psi) until the uptake of hydrogen ceases. The mixture is filtered through a pad of Celite and the pad washed well with methanol. The filtrate is concentrated under vacuo and the residue crystallized from methanol/acetonitrile to give, after filtering and vacuum drying, 4.7 grams of an off-white solid, M.P. 204°-206° C. Recrystallization from methanol/acetonitrile gave, after filtering and vacuum drying, 2.3 grams, M.P. 208°-210° C. of the hydrochloride salt.
