실험 절차

_The reaction of saturated of aqueous Na2CO3 solution (25 mL), tert-butyl 4-{[(trifluoromethyl)sulfonyl]oxy}-1,2,3,6-tetrahydro-1-pyridine-carboxylate (20 mmol), 3-acetamidophenylboronic acid (30 mmol) and tetrakis-triphenyl)phosphine palladium (0) (1.15 g) in dimethoxyethane (40 mL) at reflux temperature overnight gave tert-butyl 4-[3-(acetylamino)phenyl]-3,6-dihydro-1(2H)-pyridinecarboxylate. Deprotection of the BOC group using HCl in dioxane followed by basification (pH 11-12) gave the desired product.
