British Patent 1,040,736 EXAMPLE 1 2.3 g of para-hydroxynorephedrine are dissolved in 5 ml of water to which are added 25 ml of NH4OH (d=0.90). A solution of 5.78 g of iodine in 50 ml of 95% ethanol is added, while stirring, over a period of 45 min. The formed 1-(4-hydroxy-3,5-diiodo-phenyl)-2-aminop EXAMPLE 2 4.35 g (20 millimoles) of para-hydroxyephedrine hydrochloride are dissolved in 50 ml of distilled water to which 140 ml of NH4OH are added (d=0.90). A solution of 11.43 g (90 millimoles) of iodine in 150 ml of 95% ethanol is added, while stirring, over a period of time of 45 min. The 1-(4-hydroxy-3,5-diiodophenyl)-2-(methyl |

By all means, it should, as long as it is a 4-hydroxy derivative. There is no reason to believe that an aliphatic alcohol on the side chain should modify the reactivity at all. Also see Post 285579 (foxy2: "3,5-diiodo-4-methoxyphenethylamine", Chemistry Discourse) for the same reaction performed on tyramine. |

That complex is stable to a degree warranting only careful consideration of the material. if you keep in wet with Ammonia solution and dispose of it in a safe place (outside away from anything important) everything should be fine. let it dry for about an hour outside, then start chucking pebbles at it. fun stuff. |
