2-Pentadecyl-1,4-naphthoquinone (60 g, 0.163 mol) was suspended in acetic acid (2 l) with stirring. Aqueous 37 percent formaldehyde (200 ml, 2.4 mol) and 31 percent hydrogen bromide in acetic acid (660 ml, 2.4 mol) were added and the mixture was stirred at room temperature overnight. The precipitated product was then filtered off, washed with a minimum amount of acetic acid, water, and was then air dried. Yield: 60 g (80 percent). (Method of R. H. Thomson, J. Chem.
