反応手順

Minami et al (Chem. Pharm. Bull., 27(3), 816-820, 1979) disclose the following reaction scheme: ethyl chloroformate was added, at a temperature of 0°-5° C. and over a period of 1 hour, to a solution of 1-hydroxy-2-naphthoic acid and triethylamine in tetrahydrofuran whereby the correspondence carbamate was produced. The reaction mixture was added to a solution of sodium borohydride in water, with stirring, at a temperature of 5° to 15° C., and over a period of 1 hour. Extraction with ether gave 2-methyl-1-naphthol in a yield of 69.2%.
