実験手順
To a solution of 1,1-dimethylethyl 6-[(hydroxyamino)(imino)methyl]-5-methyl-3,4-dihydro-2(1H)-isoquinolinecarboxylate (Preparation 17; 435 mg; 1.42 mmol) in dichloromethane (10 ml) was added triethylamine (0.30 ml; 2.14 mmol) followed by 3-chloro-4-[(1-methylethyl)oxy]benzoyl chloride (Preparation 8; 365 mg; 1.57 mmol) in dichloromethane (5 ml). After 30 min, the reaction was concentrated, and the residue partitioned between ethyl acetate and saturated sodium bicarbonate. The aqueous layer was further extracted with ethyl acetate, and the combined organic layers washed with brine, dried (MgSO4) and concentrated in vacuo. Purification by flash chromatography on silica gel, eluting with a gradient of 10-50% ethyl acetate in cyclohexane gave the title compound as a white foam (413 mg).
