Reaction Steps

Following the conditions described by Miocque and Vierfond (Bull. Soc. Chim. France 1970, 1896), 2,6-diisopropylaniline (17.73 g, 0.10 mol), 37% aqueous formaldehyde (8.1 mL, 0.10 mol), piperidine (8.52 g, 0.10 mol), acetic acid (3.00 g, 0.05 mol), and ethanol (25 mL) were allowed to boil together until the temperature of the solution reached 92° C. The solution was then refluxed for 24 hours. The product was distilled under vacuum (122°-140° C. at 0.7-0.8 mm) to give the title compound (17.57 g, 64%).
