Reaction Steps

Ethyl 2-guanidino-5-thiazolecarboxylate hydrochloride (1.0 g; 3.99 mmoles) [prepared in Step A] was added to a cooled (ice-water bath) suspension of lithium aluminum hydride (0.46 g; 12.1 mmoles) in 25 ml of tetrahydrofuran. The reaction mixture was then heated at reflux temperature for 2 hours, cooled, decomposed with 0.46 ml H2O, 0.46 ml of 15% NaOH and 1.38 ml H2O and filtered. The filtrate was dried and evaporated under reduced pressure to give 0.61 g of product. Recrystallization from acetonitrile yielded the title compound, mp 168°-170°.
