Yield:3228-01-1 98%
Reaction Conditions:
with platinum(IV) oxide;hydrogen in ethyl acetate at 10; under 775.743 Torr; for 6 h;
Steps:
301.B Step B. 2-i sopropyl-3 -methylphenol .
To a solution of 3 -methyl-2-(prop- 1 -en -2- yl)phenol (3 g, 20.2 mmol, 1.0 eq) in ethyl acetate (30 mL) was added PtCh (460 mg, 2.02 mmol, 0.1 eq) under N2. The suspension was degassed under vacuum and purged with H2 several times. The mixture was stirred under H2 (15 psi) at 10 °C for 6 hours. The reaction mixture was filtered and the filtrate was concentrated to give the title compound (3 g, 98% yield). White solid. 1HNMR (400 MHz, chloroform-d) d = 6.95 (t, J= 8.0 Hz, 1H), 6.74 (d, J= 7.6 Hz, 1H), 6.56 (d, J= 8.0 Hz, 1H), 4.64 (s, 1H), 3.37 - 3.25 (m, 1H), 2.35 (s, 3H), 1.40 (s, 3H), 1.38 (s, 3H).
