Hydrochloric Acid → 2-Amino-5-tert-butyl-4-(hexadecyloxy)phenol--hydrogen chloride (1/1)

Participants

Reaction Steps

7.3 g of the benzoxazole compound obtained in Step (d) above was refluxed for 3 hours together with 30 ml of ethanol and 20 ml of concentrated hydrochloric acid. After the completion of the reaction, the reaction mixture was allowed to stand and cool. The crystals thus precipitated were collected by filtration, washed with water and then washed with acetone. Thus, 6.9 g (92% yield) of 2-amino-5-tert-butyl-4-hexadecyloxyphenol hydrochloride was obtained.
