What is ISOPROPYLMAGNESIUM BROMIDE?

Amrinone is also known as indanone and is a pyridine phosphodiesterase 3 inhibitor when inoculated. This is a drug that can improve the prognosis of patients with congestive heart failure. Amrinone has been shown to increase heart-induced contraction through high calcium-induced calcium release (CICR). The positive inotropic effect of amrinone is mediated by the selective enhancement of high-gain CICR. The highly selective CICR contributes to the contraction of cardiomyocytes through the phosphorylation of cAMP-dependent protein kinase A (PKA) and Ca. 2+ Calcium Regulatory protein kinase pathway.

Preparation of Isopropyl Magnesium Bromide

  1. Isopropylmagnesium bromide nitrogen is replaced 3 times in 500L reactor, add 25.25kg magnesium balls (0.8cm), add 100L 2-methyltetrahydrofuran and initiator (2-bromopropane Grignard reagent) 2kg, be heated to 60- Reflux at 65 degrees, slowly add the mixture of 123kg 2-bromopropane and 120L2 methyl tetrahydrofuran dropwise at 50-60 degrees to make a clear and transparent light brown to light gray liquid, reflux for 2 hours after the dropwise addition, and the acid-base titration concentration is 3.02 mol, cool down to about 10 degrees, settle for 24 hours, a small amount of black suspended solids and precipitates are deposited at the bottom of the reactor, and no other solids are precipitated, and the supernatant is hydraulically poured into a steel cylinder.
  2. Isopropylmagnesium Bromide Take a 250ml three-necked bottle, add 2.64g of magnesium powder and a catalytic amount of iodine elemental catalyst, vacuumize, fill with nitrogen, and add 20ml of ether solvent to it. 9.4 ml of isopropyl bromide and 25 ml of diethyl ether solvent were added thereto and stirred to obtain a tetrahydrofuran solution containing iPrMgBr (isopropyl magnesium bromide) after the reaction.
