Reaction Steps

To a solution of N,N-dimethylacetamide (200 ml) containing 20 g (0.0314 mol) of 2-amino-4-hexadecyloxy-5-(1,1,3,3-tetramethylbutyl)phenol paratoluene sulfonate and 12.7 ml of pyridine was added 10.6 g (0.0346 mol) of the compound obtained in Step (b) above with stirring while introducing a nitrogen gas and the mixture was stirred at room temperature for 1 hour. The reaction solution was added to 500 ml of aqueous solution containing 15 ml of hydrochloric acid and the precipitate was extracted with ethyl acetate. The ethyl acetate was washed with water and concentrated. To the residue was added 100 ml of methanol and the crystals thus precipitated were collected by filtration. Yield: 22 g (94%).
