Procedure

3-Hydroxybenzaldehyde (25.7 g, 210 mmol) was dissolved in ethanol (70 ml), and malonic acid (25.7 g) and the acetic acid salt of methylamine (38.6 g) were added to the solution. The resulting mixture was heated under reflux for 3 hours. Crystals which precipitated in the reaction mixture were collected by filtration to afford the desired compound (24.1 g).
