Yield: 93.1%

Reaction Conditions:

with caesium carbonate in acetonitrile at 160; under 0 - 8550.86 Torr; for 1 h;Microwave irradiation;

Steps:

3.1 Example 3: Methylation of other phenolic dials with dimethyl-carbonate and under m km wa ve conditions
Example 3: Methylation of other phenolic dials with dimethyl-carbonate and under m km wa ve conditions Procedure: A solution of substrate (1.074 mmo ; Table 3), Csi Oj (1 ,074 mmol), DMC (2 ml ,), mesitylene std. (100 and CHsCN (5 mL) 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 rpm. The pressure of the reaction mixture increased from 0-1 1 ,4 bar over the duration of 60/120 minutes. After 60/120 minutes, the reaction was cooled to room temperature, pressure released and the reaction mixture were analysed by GC-FID and GC- S. Results are shown in Table 3. s % yield corresponds to to-meih iated product
