Biene, i dont think that HCl in IPA without Ether is a good joice! - Most of our beeloved amine salts are more or less oluble in IPA, so you will loose some product here!
It would be better to dissolve the freebase in Toluene or Ether (if you can get some, but Toluene/Xylene might work good too!), and then add the HCl dissolved in IPA until no more crystals sprint to live!
best wishes,
