Butyl iodide → HCID 54063712, compound

Participants

Reaction Steps

To a stirred mixture of (3-n-butylamino-4-phenoxy-5-sulfamylbenzyl)methylamine (3.6 g; prepared as described in Example 115), sodium hydrogen carbonate (0.9 g) and hexamethylphosphoric triamide (15ml) a solution of n-butyl iodide (1.85 g) in hexamethylphosphoric triamide (5 ml) is dropwise added during about 1 hour. After additional stirring for 30 minutes, the mixture is diluted with water to precipitate crude (3-n-butylamino-4-phenoxy-5-sulfamylbenzyl)-n-butylmethylamine. After filtration and recrystallization twice from ethanol it is obtained with a melting point of 103°-104° C. The material (IR, analysis) is identical with the material prepared as in Example 128.
