alpha-methylpiperazine-1-ethanol

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Grams 3 of 1-(2-hydroxypropyl)piperazine and 1.6 g of 2-chloronicotinic acid in 50 ml dioxane were refluxed for 2 days. The react ion mixture was cooled, then allowed to rest for 2 days, the solvent was removed and the residue was crystallized from absolute ethanol to give 1.2 g of 2-[4-(2-hydroxypropyl)piperazin-1-yl]nicotinic acid, melting at 222°-223° C. (with decomposition). The react ion mixture was cooled the solvent was removed the residue was crystallized from absolute ethanol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
