실험 절차
According to the method of Tet. Let., 26, 1661 (1985), combine methyl 2-methoxy-5-aminobenzoate (0.5 g, 2.76 mmol) and di-2-pyridyl thionocarbonate (0.64 g, 2.76 mmol) in dichloromethane (10 mL). After 30 minutes, dilute the reaction mixture with dichloromethane and extract five times with water. Dry the organic layer over Na2SO4, filter, and concentrate in vacuo to give methyl 2-methoxy-5-thioisocyanatobenzoate: Rf=0.51 (silica gel, dichloromethane).
