Reaction Conditions:

at 205; for 20 h;Sealed tube;Temperature;

Steps:

B; B Step B. Preparation of dimethyl 4-allyl-5-hydroxyisophthalate.

Dimethyl 5- (allyloxy)isophthalate (6.1 g, 24.4 mmol) was heated in a sealed tube at 205 °C for 20 h, then cooled to room temperature to provide the desired product (6.03 g, quantitative), which was pure enough to use in the next step. NMR (400 MHz, CDCh) d 8.12 (d, J = 1.6 Hz, 1H), 7.68 (d, J = 1.6 Hz, 1H), 6.02 (m, 1H), 5.52 (s, 1H), 5.13 (m 2H), 3.93 (s, 3H), 3.92 (s, 3H), 3.83 (m, 2H).
