Procedure: A mixture of 81.1 g of 1,3,5-triethylbenzene, 60.4 g of chloromethyl methyl ether and 6.0 g of acetic acid was stirred in a sealed tube at 120° C. for 7 hours. The reaction mixture was poured into 500 ml of water and extracted with hexane. The organic layer was washed with an aqueous sodium bicarbonate solution, dried over anhydrous magnesium sulfate and then concentrated. The residue was distilled under reduced pressure to obtain 68.07 g of 2,4,6-triethylbenzyl chloride. Boiling point: 88 to 98° C. (0.18 kPa). extracted with hexane The organic layer was washed with an aqueous sodium bicarbonate solution dried over anhydrous magnesium sulfate concentrated The residue was distilled under reduced pressure

Conditions: temp:45.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a mixture of 3.00 g of 1,3,5-triethylbenzene (purity: 93%) and 5.58 g of acetic acid, 0.82 g of paraformaldehyde and 4.7 mL of a 33% solution of hydrogen bromide in acetic acid were added. This mixture was heated at 45° C. for 7.5 hours under stirring. After the reaction mixture was cooled to room temperature, 16.8 g of water and 16.8 g of toluene were added thereto. The reaction mixture was separated. The organic layer was washed sequentially with 11.2 g of water, a mixture of 5.6 g of an aqueous saturated sodium hydrogen carbonate solution and 5.6 g of water, and 11.2 g of water, dried over anhydrous magnesium sulfate, and then concentrated to obtain 4.72 g of 2,4,6-triethylbenzyl bromide (GC-area: 84%) as a yellow oil. were added After the reaction mixture was cooled to room temperature The reaction mixture was separated The organic layer was washed sequentially with 11.2 g of water a mixture of 5.6 g of an aqueous saturated sodium hydrogen carbonate solution and 5.6 g of water, and 11.2 g of water dried over anhydrous magnesium sulfate concentrated
