Methanol → AGN-PC-0NFNDG

181.4 g (1.0 mol) of dodecylamine, 104.1 g (1.0 mol) of ethyl glycolate and 7.5 g (40 mmol) of a methanol solution containing 28% sodium methylate were fed into a 500-ml four-necked flask equipped with a stirrer and a thermometer. The obtained mixture was stirred under a stream of nitrogen gas, and the temperature thereof was elevated to 100° C. At this temperature, the reaction mixture was stirred for 2 hr while distilling off formed methanol. The obtained reaction mixture was dissolved in 500 ml of ether at room temperature. The ether solution thus obtained was transferred to a separatory funnel, and washed with water. The ether phase was separated, and concentrated. The solid remaining after concentration was dried in a reduced pressure to thereby obtain 182.3 g of white powdery N-dodecylglycolamide (yield: 74.9%). The hydroxyl value of this N-dodecylglycolamide was 229.4 (calculated value: 230.5).
