I actually saw this amine offered in one of the Sigma Aldrich catalogs and was being sold as a standard for Schedule 1 'Drugs of abuse', go figure. From what I have been able to glean, you want to do the Al/amalgum RDXN which would be done with an XS of amine in a hydroalcoholic soln. If you are attempting this method for propiophenone, there will be some trouble due to the aromatic ring pulling the reactivity of the ketone [hindered] unlike the 2 position which is quite reactive. When you do react a ketone in the "2" position via the aforementioned method, be sure to add enough alcohol to get a clear soln., have at least a 3 molar XS of amine, and let your soln. sit for a 24 hr minimum prior to adding the amalgum foil. Xperience has taught us that the rxn proceeds much cleaner and with higher yields and less 'glop' to clean out afterwards. For hindered amines there is only one method that I like and it's inexpensive and not labor intensive. Set up a reflux with a Barret water trap and an Allihn condenser with a one molar soln of ketone and 1.05M of amine in Xylene and a few crystals of p-TSOH-H2O. If the RXN goes well you will collect ~18mL of H2O in the trap and trapped the 'imine' intermediate in the xylene. Reflux off the xylene at 80 C using a water aspirator to get the imine; you can leave some xylene behind. Dissolve the cooled imine soln. in 99% IPA and slowly add .30 M of NaBH4 with stirring and mild heating after the complete addition. Slowly add H2O [1 mL every 5 min] and the borohydride complex will break down and the RDXN complete. There are other methods like NaBH3CN but that is now inferior to Na[OOCCH3]3BH; the former is poisonous and the latter is expensive. My method is inexpensive and will work for your situation plus you get a near theoretical yield of trapped intermediate; it's all downhill from there. I didn't get into too much detail but I think you will sort it out.
