Application of 133232-56-1, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 133232-56-1 as follows.

3-Iodo-2-methylbenzoic acid (10.00 g, 38.16 mmol), methanol (50 ml) and concentrated sulfuric acid (0.6 ml, 11.45 mmol) were mixed, and the mixture was stirred for 5 hours while heating to reflux. The reaction solution was concentrated, ethyl acetate (80 ml) and water (30 ml) were added to the residue. The organic layer was separated and washed three times with a saturated aqueous sodium bicarbonate solution (30 ml) and once with 10% brine (30 ml) . The organic layer was concentrated, to yield the title compound (9.22 g) (yield 87.5%) .1H-NMR (CDCl3, TMS, 300 MHz) delta (ppm) : 2.67 (3H, s) , 3.90 (3H, s), 6.92 (IH, t, J = 7.8 Hz), 7.74 (IH, dd, J = 1.2 Hz, 7.8 Hz) , 7.98 (IH, dd, J = 1.2 Hz, 7.9 Hz) .
