实验步骤: 5.4 g (0.02 mol) of the 11-(3-chloropropylidene)-6,11-dihydrodibenzo-[b,e]-oxepine, prepared according to (c) above, in 20 mL tetrahydrofuran and 5.5 g (0.12 mol) dimethylamine in 20 mL ethanol is heated together for 3 hours using a glass autoclave and a temperature of 95-100° C. (boiling water bath). Water and 6 N hydrochloric acid are added to the contents of the autoclave and the mixture is extracted with ether. The separated, aqueous-acid components are then made alkaline with dilute caustic soda solution, and the oil thereby separated is taken up in ether. The ether residue, after distillation in a high vacuum, produces 4.1 g (73.5% of theory) of 11-(3-dimethylamino-propylidene)-6,11-dihydrodibenzo-[b,e]-oxepine, having a B.P.0.1 147-150° C. The melting point of the hydrochloride is 182-184° C. (recrystallized from isopropanol). the mixture is extracted with ether the oil thereby separated The ether residue, after distillation in a high vacuum

实验步骤: A 2% composition of doxepin in the nanolipid-vesicle composition of Preparation 2 above was prepared by mixing doxepin hydrochloride with the nanolipid vesicle formulation as described in Preparation 2 which had been modified by the addition of Keltrol to render a thick creamy consistency, in a mass/mass ratio of 2:98 with the aid of a high speed stirrer. The composition is designated DOXIPEX CREAM. (b) In similar manner a 1.7307% composition of Lidocaine Hydrochloride was prepared and designated LIDAREX LOTION. (c) A 0.3% composition of Scopolamine HBR was also prepared in the same manner and designated MZL Scopolamine. (d) A 0.5% nasal spray composition of Oxymetazoline HCl was also prepared in the same manner with some modification and designated Oxymetazoline MZL. (e) A 0.5% injection formulation of Bupivicaine HCl was further prepared in the same manner but with some modification and designated Bupivicaine MZL. above was prepared as described in Preparation 2 which had been modified by the addition of Keltrol

实验步骤: Doxepin hydrochloride (10 g., 0.032 mol) was dissolved in 50 ml. H2O. Sodium bicarbonate (3.2 g., 0.038 mol) suspended in 25 ml. of H2O was added with stirring, and the mixture stirred for 20 minutes and then extracted 3×50 ml. ether. The ether extracts were combined, dried (Na2SO4) and evaporated in vacuo to yield doxepin as an oil (8.33 g.). the mixture stirred for 20 minutes extracted 3×50 ml dried (Na2SO4) evaporated in vacuo
