실험 절차

To a cooled with an ice bath solution of (S)-tert-butyl 3-(acetylthiomethyl)-4-((R)-2-hydroxy-2-(4-methyl-1-oxo-1,3-dihydroisobenzofuran-5-yl)ethyl)piperazine-1-carboxylate (573 mg, 1.233 mmol) in anhydrous toluene (12.3 mL) was added thionyl chloride (0.268 mL, 3.70 mmol). Then, anhydrous pyridine (0.399 mL, 4.93 mmol) was added dropwise. The reaction mixture was kept at 0° C. for 20 min, then warmed to room temperature and stirred for 3 hours. TLC showed the consumption of the starting material. The reaction was concentrated under reduced pressure and dried on high vacuum overnight. Used directly in the next step.
