2-methylpiperidine, (±) synthesis

15synthesis methods
-

Yield:3000-79-1 86%

Reaction Conditions:

with zirconium(IV) oxide at 350;Inert atmosphere;

Steps:

5 Example 5.

0.3 g of silicon oxide (Q-6) was filled in a quartz reaction tube,1.60 cm 3 / h of 6-amino-2-hexanol,Nitrogen gas was flowed at 20 cm 3 / min, and the reaction was carried out at 350 ° C.As a result of analyzing the product by gas chromatography,The conversion of 6-amino-2-hexanol was 75%The selectivity of 1-methyl-piperidine was 88%The reaction yield of 1-methyl-piperidine was 66%.; Except for replacing silicon oxide (Q-6) in Example 4 with zirconium oxide (tetragonal)The gas phase reaction was carried out according to the method described in Example 4.As a result of analyzing the product by gas chromatography,The conversion of 6-amino-2-hexanol is 95%The selectivity of 1-methyl-piperidine is 90%The reaction yield of 1-methyl-piperidine was 86%
