If want to buy good and cheap, I suggest you still purchase from China, including chemical raw materials and equipment, both convenient oneself also help oneself save cost.

why you do it,if a Chinese buyer cheap you?

 This requires suitable conditions. It's an addition reaction

If this Grignard reaction is not ideal, o-chlorobenzaldehyde can be used, which is easy to react to produce alcohol and then oxidize.

 Both magnesium sulfate and sodium sulfate can be used, but the sodium sulfate crystal is relatively large and easy to deposit at the bottom, which is good

 You can use hydrochloric acid, then concentrate and dry under reduced pressure, and add acetonitrile or acetone for dispersion and filtration

Then use the method of palladium carbon debenzylation. The post-treatment is simple, and the by-product is also easy to treat. The post-treatment is suction filtration and vacuum concentration. The by-product is toluene.

 Yes, there are many methods for debenzylation

Add 5% to 10% by mass, because amino will weaken the catalyst activity, and the catalyst may be 10%

yes，don't work

Raney nickel cannot be used for debenzylation reaction

 This reaction must not use Raney nickel, palladium carbon can be reduced to 5% to 10%, and chloroethyl chloroformate can also be used

The amount of pd/c is much too many。

thanks,I don't need it,but I can provide you some materials.

1-phenylacetone is not easily available and can be reacted with 1-phenylisopropanol and methylsulfonyl chloride to get methanesulfonate, and then methylsulfonyl and methylamine reaction solution can get the target product.

I can provide you all kinds of product in law.
