실험 절차

4-Iodobenzoyl chloride (10.0 g) was added portionwise to piperidine (3.53 g) in triethylamine (40 ml) at 0° and the suspension was stirred at room temperature under nitrogen for 1 h. The reaction mixture was poured into 2N aqueous hydrochloric acid (200 ml) and extracted with EA (3×100 ml). The combined extracts were washed with water (100 ml), 8% aqueous sodium bicarbonate (100 ml) and water (10 ml), dried and concentrated. The resultant solid (10.25 g) was purified by FCC eluting with ER-H (1:2→1:1) to give the title compound as a white solid (9.33 g) m.p. 126°-127°.
