실험 절차

Methyl 2-((3-methyl-4-nitroisothiazol-5-yl)carbamoyl)benzoate was suspended in MeOH (30 mL), Pd/C 10% (477.1 mg, 4.483 mmol) was added and the mixture was hydrogenated at RT under 1 atm of hydrogen (balloon pressure) for 2 h. The catalyst was filtered off and the mixture was concentrated in vacuo, yielding methyl 2-((4-amino-3-methylisothiazol-5-yl)carbamoyl)benzoate. (150 mg, 100%). MS (ES+) 292.1.
