Reaction Steps

Compound 93 (1.15 g, 0.32 mmol) was dissolved in trifluoroacetic acid (12 mL), followed by stirring at room temperature for 30 minutes. The reaction mixture was concentrated under reduced pressure, and aqueous 1 mol/L sodium hydroxide solution and a mixed solvent (4:1) of chloroform and 2-propanol were added to the resulting residue, and the organic layer was separated. The organic layer was dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure to afford 2-amino-4-(2-furyl)-5-morpholinomethylthiazole (835 mg, 100%).
