Preparation of p-Methyl anisole: it can be prepared by p-cresol and dimethyl sulfate in the presence of sodium hydroxide through methylization. And then after a series of neutralization, washing, separation and vacuum distillation you can get the desired product. In addition, it can be obtained by (4-methoxy-phenyl)-methanol. This reaction will need reagents sodium borohydride and TFA, and solvent tetrahydrofuran. The reaction time is 1 hours at reaction temperature of 25 °C. The yield is about 19%.

p-Methyl anisole can be obtained by (4-methoxy-phenyl)-methanol

Uses of p-Methyl anisole: it can be used as food flavors for baked goods, pastes and frozen dairy products. In addition, it can be used to get 4-methoxy-benzaldehyde. This reaction will need reagent 3,6-bis(triphenylphosphonium)cyclohexene peroxodisulfate, and solvents acetonitrile and H2O. The reaction time is 25 minutes by heating. The yield is about 95%.

p-Methyl anisole can be used to get 4-methoxy-benzaldehyde.
