Yield:234751-02-1 98%
Reaction Conditions:
with triethylamine in 1,4-dioxane at 80;
Steps:
1.2 Step 2
Weigh the appropriate compound IVa (1eq) in a 100ml round bottom flask,Put it in the rotor, measure 30ml of dioxane and add it to the reaction bottle as a solvent.Add the weighed triethylamine (3eq) and isopropylamine (2eq) to the reaction bottle in sequence.React at 80 ° C. After the IVa reaction is complete, remove the reaction flask and cool to room temperature.The solvent was spin-evaporated and pumped by an oil pump to finally obtain Va as a yellow solid product (yield: 98%).
