2-(3-(3-fluorobenzyl)ureido)thiazole-4-carboxylate (4.08 mmol) is taken up in THF and solution is cooled to −78° C. Added LiAlH4 (2.6 equivalents, 1M solution in THF). Stir at ambient temperature for 3 hours. Add slowly Na2SO4.10H2O (6.4 g), then NaHSO4 (1.8 g). Stir for 30 hours. Aqueous workup with EtOAc. Crystallized from DCM/hexanes to give 1-(3-fluorobenzyl)-3-(4-(hydroxymethyl)thiazol-2-yl)urea in 79% yield.
