Procedure for the Synthesis of 1,3,5-trimethoxybenzene2 Benzene-1,3,5-triol (0.126 g, 1.0 mmol) was dissolved inacetone (20 mL), K2CO3 (0.55 g, 4 mmol) was added, stirredfor a while, and then dimethyl sulfate (0.2 mL, 2 mmol) wasadded dropwise at room temperature for 6 h. The resultingmixture was poured into water when the starting materialdisappeared, extracted with ethyl acetate, the organic phasewas separated and dried over anhydrous MgSO4. The organicphase was concentrated under reduced pressure to give awhite solid 2.Yield: 80percent; 1H NMR (CDCl3, 400 MHz, ppm): 6.08 (s,3H), 3.77 (s, 9H).

Conditions & References 5.2 : Example 5: Methylatwn of 1,3,5-benzenetr l with dimethylcarhonate and CG under m icro wa ve conditions Example 5: Methylatwn of 1,3,5-benzenetr l with dimethylcarhonate and CG under m icro wa ve conditions Procedure: A solution of 1 ,3,5-trihydroxybenzene (1.074 mmol), CssCO (.1.074 ιηιηο), DMC' (2 ml), mesitylene std. (100 μ}3 and CHjC (5 niL) were heated in a 30 mL air tight glass vessel in an Anton Paar Monowave 300 microwave synthesis reactor at 160 °C with a stir rate of 600 rpro. The pressure of the reaction mixture increased from 0- 1 1.4 bar over the duratio of 120 minutes. After 120 minutes, the reaction was cooled to room temperature, pressure released and heated further 240 minutes respectively, and the reaction mixtures were analysed by GC-FID and GC-MS. Results are shown in Table 5. * percent yield corresponds to ^meth lated product In. the experiments in Table 5, the starting to-hydroxy compound is not observed in the GC-FID results. This could be because the tri-rnethoxy product is the only compound formed or because the mono-methoxy-dihydroxy compound does not pass through the GC column.
