Вещи эти самосветящиеся, выказывают сверхъестественную яркость цвета и обладают сверхъестественной значимостью. Материальными предметами, наиболее близко напоминающими эти источники визионерского освещения, являются самоцветы. Получить подобный камень значит получить нечто, ценность чего гарантирована тем фактом, что оно существует в Ином Мире.
A solution of 6.96 g 2,5-dimethoxyamphetamine hydrochloride (2,5-DMA) in 250 mL H2O was made basic with aqueous NaOH and extracted with 3x75 mL CH2Cl2. After removal of the solvent from the pooled extracts under vacuum, the residual free base was dissolved in 36 g glacial acetic acid and, with good stirring, cooled to 0 њC with an external ice bath. There was then added, with a Pasteur pipette, 3 mL of liquid chlorine. The generation of HCl was evident, and the reaction was allowed to stir for an additional 3 h. The mixture was then poured into 300 mL H2O and washed with 3x100 mL Et2O. The aqueous phase was made basic with NaOH and extracted with 3x150 mL CH2Cl2. After removal of the solvent from the pooled extracts, the residue was dissolved in Et2O and saturated with anhydrous HCl gas. There was the formation of a heavy oily precipitate. The ether supernatent was decanted, and the residue was intimately mixed with 200 mL of fresh anhydrous Et2O. Everything set up as an off-white crystalline mass weighing 2.3 g. This was dissolved in 12 mL of boiling MeOH and diluted with 230 mL boiling Et2O. The clear solution was quickly filtered to give a clear, pale amber mother liquor, which soon started depositing lustrous white crystals. After filtering, Et2O washing, and air drying to constant weight, there was obtained 1.4 g of 2,5-dimethoxy-4-chloroamphetamine hydrochloride (DOC) From the mother liquors (from the original HCl saturation) an equal amount of product could be obtained by exploiting the acetone insolubility of the hydrochloride salt of the product. The published mp of this salt, from acetone/EtOH, is 187-188 њC. A sample of this hydrochloride salt, prepared from the amino analogue via diazotization and eventual hydrolysis of an acetylated precursor, was recrystallized from EtOH/ether and had a mp of 193-194.5 њC.

- вы не задумывались, почему этот смайл называется не иначе как mda - MethylenDioxyAmphetamine?
