Yield:91763-35-8 319 g

Reaction Conditions:

with aluminum (III) chloride;sodium tetrahydroborate in 1,2-dimethoxyethane at 20 - 50; for 4 h;Large scale;

Steps:

1.2

The second step:Add M1 300g, ethylene glycol dimethyl ether 2000g, sodium borohydride 70g, and stir in a 5L reaction flask.Add 82g of aluminum trichloride in batches at room temperature, add 2 hours, the system will automatically heat up, and finally keep warm at 50 °C for 2 hours.Sampling plate analysis, the reaction is over, and the reaction is stopped.Pour into ice water for hydrolysis, adjust to pH=2 with sulfuric acid, extract with ethyl acetate, wash with 10% sodium bicarbonate until neutral, separate the liquid, and steam the solvent.Obtained intermediate M2(319 g, molar yield 90%, HPLC purity 98.6%).
