| Abstract: | An efficient synthesis of the photochromic 5-methyl-spirooxazine is reported.2, 3, 3, 5-Tetramethyl-3H-indole, as a key intermediate for this synthesis is prepared by the Mohlau-Bischerreaction between 4-methyl aniline and 3-bromo-3-methyl-2-butanone, which start from the bromationof the corresponding ketone in CCl4 and the absence of catalyst. The modified procedure is describedfor the condensation cyclization of 5-methyl-Fisher k base and 1-nitroso-2-naphthol. The mechamismsof relative reactions are proposed and a photochromic ink is formulated. |
