(https://www.thevespiary.org/rhodium/Rhodium/chemistry/25.meo.allylbenzene.html). In short, p-methoxyphenol is reacted with allylbromide to yield the corresponding ether, which is subsequently subjected to a Claisen rearrangement. The 2-hydroxy-5-methoxyallylbenzene obtained this way can be methylated (the article uses DMS but there probably are alternatives, such as phosphate esters - UTFSE) and voila, you have 2.5-dimethoxyallylbenzene.Chloro/Bromo/Iodosafrole Synthesis Notes (https://www.thevespiary.org/rhodium/Rhodium/chemistry/halosafrole.txt)
(https://www.thevespiary.org/rhodium/Rhodium/chemistry/halosafrole.txt). Substitution of the halogen compound is documented on Rh's site as well as on the forum - UTFSE.Post 354784 (https://www.thevespiary.org/talk/index.php?topic=12028.msg35478400#msg35478400)
