Reaction Steps

Reaction of aryl carboxamides with radiation. Aqueous 100 μM solutions of procainamide (4-amino-N-(2-diethylamino-ethyl)benzamide), 3-chloro-procainamide (N-(2-diethylamino-ethyl)-4-amino-3-chlorobenzamide), metoclopramide (4-amino-5-chloro-N-(2-diethylamino-ethyl)-2-methoxybenzamide), nicotinamide and N-(2-diethylamino-ethyl nicotinamide were given 1000 Gy of irradiation from 137cesium source (1.3 Gy/min., Scanditronix) at room temperature for 30 min. The various reaction mixtures were then vacuum evaporated to dryness, redissolved in methanol, spotted on silica gel 60 F245 thin layer chromatography (TLC) plates in 1-butanol:acetic acid:water (4:1:1, v/v/v), and visualized with short and long wave ultraviolet light and also in an iodine chamber, and the Rf values calculated in the conventional manner.
