실험 절차

Boc-L-Proline (9.7 g, 45.2 mmol), 4-phenyl-1,2,3,-thiadiazol-5-amine (4.0 g, 22.6 mmol), EDC (8.2 g, 42.9 mmol), HOBt (5.8 g, 42.9 mmol), DIPEA (19.7 ml, 113 mmol) were combined and stirred for 3 days in 40 ml DMF at 60 deg C. Ethyl acetate and saturated aqueous NaHCO3 were added. The aqueous layer was separated and extracted with ethyl acetate. Organic layers were combined and washed with aqueous NaHCO3 and brine. Organic layer was dried over MgSO4 and concentrated to a brown residue. Pure Boc-prolyl-4-phenyl-5-amino-1,2,3-thiadiazole c was obtained by crystallization from 100 ml hot acetonitrile to obtain 5.9 g. Calculated mass 374.5. found 375.3.
