Reaction Steps

To a solution of (R)-2-aminobut-3-yn-1-ol trifluoroacetate (601 mg) in ethanol (15 mL) were added 4-thioxo-1,3-thiazolidin-2-one (402 mg) and N-ethyl-N-(1-methylethyl)propan-2-amine (1.63 mL), and the mixture was heated under reflux overnight. The reaction mixture was concentrated under reduced pressure, the residue was purified by silica gel column chromatography (NH, methanol/ethyl acetate), and the obtained powder was washed with ethyl acetate to give the title compound (112 mg).
