Rhodium (Chief Bee) 04-11-04 18:33 No 500286				Ephedrine O-Phosphate -> Meth (Rated as: excellent)
						L-, D-, and DL-Ephedrine Phosphates A. Larizza, G. Brancaccio, A. Segre J. Med. Chem. 9, 966-967 (1966) (../rhodium/pdf /meth.ephedrine.phosphate.pdf) Reaction of L-Ephedrine with POCl3 gave L-2-Chloro-3,4-dimethyl-5-phenyl-1,3,2-oxazophospolidine 2-oxide, which upon hydrolysis yielded L-Ephedrine O-phosphate Hydrochloride. Catalytic hydrogenation of 2.8g of the ester salt using 0.28g 5% Pd-C (2h, 1 atm, 22°C) in 40 mL ethanol gave, after filtration, acid/base extraction and distillation of the freebase (bp 91-93°C/15 mmHg) 1.2 grams of product amine (84% yield).

						Rhodium, you should specify that it is from O-phosphate ester of ephedrine.  The title could imply the amine salt.  (which is how I read it coming into the thread.) However, a very nice procedure with decent yield!  What search path yielded this nugget? (key words that you used in what database- if you can tell such things) Act quickly or not at all.

						It's from the reference list at the end of ../rhodium /amphetamine.reduction.html I'm trying to link up the entire reference list to the original literature (or the pertinent sections from the referenced article). The Hive - Clandestine Chemists Without Borders
