Purpose

Representative drugs among phenothiazines. It has a stabilizing effect on the central nervous system in small doses, and has an antipsychotic effect when used continuously in large doses. This product inhibits the subthalamic thermoregulatory center, causing the body temperature to rise and fall with the ambient temperature. It can be used with other drugs to reduce the body temperature to below normal body temperature, and improves metabolism. Reducing is called artificial hibernation. Mainly used for antipsychotics, enhancing the effects of hypnotics, anesthetics, analgesics and anticonvulsants. It can also be used to relieve vomiting and intractable hiccups and induce artificial hibernation.

Storage method

Synthesis method

1. Obtained from ethyl lactate through oxidation and bromination: ethyl lactate, NBS (N-bromododecimide) and tetrachloride Add carbon dioxide into a dry reaction pot and heat to reflux for 5.5 hours while stirring. Cool and filter, evaporate the carbon tetrachloride from the filtrate, distill under reduced pressure, and collect the 71~73°C (0.67kPa) fraction, which is ethyl bromopyruvate.

2. Preparation method:

Into a reaction bottle equipped with a stirrer, thermometer, and reflux condenser, add 66g (0.56mol) of freshly steamed ethyl lactate (2), 900mL of carbon tetrachloride, and 200g of NBS ( 1.14mol), heated to (77±1)°C in a water bath, stirred and refluxed for 5 to 6 hours, until the reaction solution changed from red to orange. Hydrogen bromide gas is released during the reaction. Place in ice-salt bath overnight and filter out succinimide. After the filtrate is distilled under normal pressure to recover carbon tetrachloride, it is distilled under reduced pressure and the fraction at 71~73?/0.67kPa is collected to obtain a yellow transparent liquid ethyl bromopyruvate (1)?56.8g, The yield is 52%. nD251.465?1.4673. Note: ? It has a strong tear-inducing effect. Store it in a refrigerator after being airtight. [1]
