Procedure

A 5-liter flask fitted with an overhead stirrer and condenser was charged with di-N-butyl amine (61 g, 0.47 mol) and acetic acid (56 g, 0.9 mol). Roughly 900 ml of 37% formaldehyde solution in water (351 g formaldehyde, 11.7 mol) was then added and the resulting solution was heated to 50° C. with stirring. After this temperature was reached nonanal (1000 g, 7.0 mol) was fed in over about 2 h. A slight exotherm was noticed during the feed. Monitoring by GC showed the consumption of nonanal and the production of 2-methylene nonanal, finally reaching roughly 95% conversion after the addition was complete. The reaction mixture was allowed to cool to room temperature, poured into a separatory funnel, and washed once with 5% HCl solution. The organic layer was then washed once with saturated sodium bicarbonate, then taken directly on to the next step.
