YieldReaction ConditionsOperation in experiment
With potassium carbonate; 4-Me-3-OBN-benzaldehyde was made as shown in FIG. 1. 17.56 g of starting material yielded 13.6 g of the final product.
With potassium carbonate; In acetone; at 20℃; As outlined in Scheme I, conversion A, benzyl bromide (1 equivalent) is added to a suspension of 5-bromo-2-methyl phenol (1 equivalent) and potassium carbonate (2 equivalents) in acetone. The reaction mixture is stirred at room temperature. After completion of the reaction, the mixture is filtered, concentrated, and the residue is purified by column chromatography to yield the phenol protected as its benzyl ether
With potassium carbonate; In acetone; at 23℃; 4-Bromo-5-ethyl-2-methyl phenol (5): Compound 5 is synthesized from commercially available 5-bromo-2-methyl phenol in accordance to (a) Scheme I Conversion A, B, and C, and Scheme III Conversion A". Scheme I Conversion A: As outlined in Scheme I, conversion A, benzyl bromide (1 equivalent) is added to a suspension of 5-bromo-2-methyl phenol (1 equivalent) and potassium carbonate (2 equivalents) in acetone. The reaction mixture is stirred at room temperature. After completion of the reaction, the mixture is filtered, concentrated, and the residue is purified by column chromatography to yield the phenol protected as its benzyl ether, Scheme I intermediate I2. Scheme I Conversion B: Intermediate I2 (1 equivalent) is dissolved in anhydrous THF and cooled to -78 C. To this cold solution tert-BuLi (1 equivalent) is added drop wise and the reaction is stirred for 30 minutes. N-methoxy-N-methyl- acetamide (1.2 equivalents) is then added drop wise and the reaction is allowed to warm to room temperature. After completion of reaction, the reaction mixture is quenched with dil HCl and extracted with ethylacetate. The organic extracts are dried over anhydrous sodium sulfate, and concentrated in vacuo. The residue is purified by column chromatography to give intermediate I3. Scheme I Conversion C: A suspension Intermediate I3 and catalytic amount of 5% Pd/C in methanol under hydrogen atmosphere is stirred for 12 hours. The reaction mixture is carefully filtered over a plug of Celite and the solvent is removed in vacuo. The residue is purified by column chromatography to yield the 5-ethyl-2-methyl phenol, Scheme I intermediate I4. Scheme III conversion A": The intermediate I4, obtained above is brominated at 4-position using -BuNBr3 in a mixture of CH^C^MeOH (3:2), following the procedure described for the synthesis of compound 9 to obtain compound 5.
