p-Chlorophenol (64 g.) and 100 g. 96% H2SO4 heated to 60-70°, treated dropwise with 90 g. iso-PrOH 0.5-1 h. and then with 50 g. 96% H2SO4, the soln. heated 8 h. at 75°, poured onto ice, C6H6 added, the C6H6 layer washed with dil. NaHCO3, 10% NaOH, and H2O, and distd. gave 10 g. 2-methyl-4-chlorophenol, b7 121-36°, and 36 g. 2,6-dimethyl-4-chlorophenol (I), b7 132-5°; α-naphthylurethanes, m. 154° and 173°, resp. I (10 g.) in 50 cc. C6H6, 1 g. 1:1 Ni-Al alloy, and 165 cc. alk. soln. (15 g. NaOH in 510 cc. H2O) was heated 4 h. under initial H pressure of 29 kg./sq. cm. The pressure decreased suddenly at 120° and the final pressure was 18 kg./sq. cm. The mixt. filtered, the alk. layer acidified, extd. with C6H6, and distd. gave 6.2 g. 2,6-diisopropylphenol, b7 110-18°; α-naphthylurethane, m. 163-4°.
