الإجراء التجريبي

To a solution of 1-cyclohexyl-3-(5-formyl-thiazol-2-yl)-1-(trans-4-methyl-cyclohexyl)-urea (175 mg, 0.5 mmol) in MeOH (5 mL) was added sodium borohydride (38 mg, 1 mmol). The mixture was stirred at rt for 10 min and the solution was poured into water (25 mL). The aqueous layer was extracted with ethyl acetate (2×20 mL). The organic layer was washed with water (2×20 mL), brine (1×20 mL), dried (anhydrous Na2SO4) and concentrated to get trans-1-cyclohexyl-3-(5-hydroxymethyl-thiazol-2-yl)-1-(4-methyl-cyclohexyl)-urea in (90%, 158 mg) yield.
