How is 1-(Azidomethyl)-4-methoxybenzene (CAS: 70978-37-9) typically synthesized?

1-(Azidomethyl)-4-methoxybenzene (CAS: 70978-37-9) is typically synthesized via the azidation of 4-methoxybenzyl bromide in the presence of a base like potassium tert-butoxide. The reaction is generally conducted in an inert solvent such as THF or DMSO at low to moderate temperatures. The use of azide reagents in the presence of a suitable catalyst can enhance the selectivity and yield of the product, making the process efficient for industrial-scale production.
