1-(2-氨基-1,1-二甲基乙基)哌啶

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 4.57 g of 4,7-dichloroquinoline, 7.5 g of 2-methyl-2-(piperidin-1-yl)-propylamine and 0.75 g of phenol were reacted at 180° C. for 16 hours. The crude reaction product, isolated as in the preceeding Example, was purified on 200 g of aluminium oxide (activity grade II) prior to recrystallization; a 1:1 mixture of toluene and acetone was used as the eluent. After a fore-run, which contained unreacted 4,7-dichloroquinoline, the product was eluted and, after recrystallization from 5 ml of acetonitrile, yielded 0.8 g of colourless crystals, m.p.: 143°-147° C. The crude reaction product was purified on 200 g of aluminium oxide (activity grade II) to recrystallization a 1:1 mixture of toluene and acetone the product was eluted after recrystallization from 5 ml of acetonitrile

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: From 8.56 g. of ethyl 2-oxo-1-pyrrolidineacetate and 12.5 g. of 2-methyl-2-(1-piperidinyl)propylamine [J.A.C.S. 68, 13 (1946)], following the procedure of Example 9, there is obtained N-[2-methyl-2-(1-piperidinyl)propyl]-2-oxo-1-pyrrolidineacetamide; m.p. 69° C. after crystallization from heptane.
