実験手順

A stirred mixture of 4-amino-5-chloro-N-[2-(diethylamino)ethyl]-2-hydroxybenzamide hydrochloride (10.0 g, 31.06 mmoles) (from Preparation No. 1A), anhydrous potassium carbonate (12.84 g, 93.16 mmoles), sodium iodide (4.66 g, 31.06 mmoles) and 2-chloroethyl methyl sulfide (3.70 ml, 4.10 g, 37.26 mmoles) in 60 ml of dry DMF was refluxed for 10 hours. The solvent was evaporated under reduced pressure and the dark semi-solid was partitioned between water and methylene chloride. Sodium hydroxide solution was added to bring the pH of the aqueous layer to 14. The mixture was shaken well and the layers were separated. The aqueous layer was extracted with 3 portions of methylene chloride. The combined organic solutions were dried over MgSO4 and evaporated. The solid obtained was dissolved in 100 ml of warm acetonitrile. The solution was treated with Darco G-60, filtered, evaporated to 30 ml, and stored at -15°. The solid was filtered to give 3.56 g (32%) of the title compound as off-white crystals, mp. 118°-120°.
