Versuchsvorschrift

To a magnetically stirred solution of 2-amino-5-chlorobenzophenone (1.62 g, 7.0 mmol) in dry pyridine (30 mL) was added dropwise a solution of pipsyl chloride in toluene (12 mL) and the reaction was stirred at ambient temperature. The reaction was added to cold (ice bath) 6M hydrochloric acid with stirring and the mixture was extracted with ethyl acetate (3×50 mL). The extracts were washed with water and with saturated aqueous NaCl. The organic layer was dried (MgSO4), filtered and concentrated to give a crystalline solid. The product was filtered, washed with hexane and dried (vacuum) to get white crystalline solid. 1H NMR (CDCl3) δ 9.63 (br s, 1H, NH), 7,75 (dm, 1H, J=8.8 Hz), 7.62 (tm, 1H, J=7.6 Hz), 7.56 (dm, 1H, J=7.6 Hz), 7.48 (m, 3H), 7.32 (m, 5H). MS: m/z 498.0 (M+1).
