2-(4-Allyl-1-piperazinyl)-4-pentyloxyquinazoline → HCID 14424735, compound

Participants

Reaction Steps

Ethanol (25 ml) was added to 2.3 g of maleic acid, and the mixture was heated to form a solution. A solution of 3.4 g of 2-(4-allyl-l-piperazinyl)-4-pentyloxyquinazoline in 5 ml of ethanol was added to the solution. The mixture was cooled, and the precipitated crystals were collected by filtration and recrystallized from 90 % ethanol to give 3.3 g of 2-(4-allyl-l-piperazinyl)-4-pentyloxyquinazoline dimaleate as colorless needles.
