    • A 25 mL round bottom flask with a magnetic stir bar was flame dried. Paraformaldehyde (1.2g, 13.3 mmol) (equiv to 40 mmol of formaldehyde) in absolute ethanol (10 mL) and KOH (100 mg) were added. The solids were dissolved by warming the flask (40-45 °C). The appropriate amine (40 mmol) was added dropwise to the reaction while cooling with an ice bath. The reaction was stirred for 1 h and was diluted with absolute ethanol (30 mL) to make a 1 mM stock solution of the Mannich reagent (5a-e).
