실험 절차

A solution of tin chloride dihydrate (5.44 g, 24.1 mmol) in concentrated hydrochloric acid (32 ml) was added slowly to a cooled, stirred solution of (4-nitro-phenyl)-(4-phenyl-piperazin-1-yl)-methanone (1.0 g, 3.2 mmol) in anhydrous diethyl ether (32 ml). The resulting mixture was stirred for 1 hour at room temperature, then cooled and quenched carefully with 10M sodium hydroxide (aq.) until slightly basic (˜pH 9). The aqueous mixture was extracted with ethyl acetate (100 ml) and the organic extracts dried over magnesium sulfate then concentrated in vacuo to the title compound as a cream solid (667 mg, 73% yield). HPLC retention time 6.2 min. Mass spectrum (ES+) m/z 282 (M+H).
