Reaction Steps
α-(Aminomethyl)-3,4-dimethoxybenzyl alcohol hydrochloride (2.88 g) and 2-acetamido-4-formyl-thiazole (2.1 g) were suspended in 14 ml methanol, and 1.8 ml triethylamine was added dropwise to this suspension with stirring. The resulting solution was heated under reflux for 30 minutes, and 0.70 g sodium borohydride was added in small portions with stirring under ice cooling. The crystals which separated out were collected by filtration, washed with water and methanol in that order and vaccum-dried, giving 3.55 g of α-[[[(2-acetamido-4-thiazolyl)methyl]amino]methyl]-3,4-dimethoxybenzyl alcohol, m.p. 204°-206° C.
