HCl does not add easily to safrole, you need an excess of HCl and a PTC (see my halosafrole document on my page). Iodized table salt contains very little NaI (or NaIO3) and is of no use. A finkelstein swap of Chlorosafrole/NaI/acetone would work though. Iodosafrole would probably distill at about 150-160°C at aspirator vacuum. Some dehydrohalogenation would probably occur if not a high vacuum is used.
