Procedure

Thiourea (0.5 mole), formaldehyde (1 mole of 37% aqueous solution) and 200 ml. dioxane were placed in a 1 l. round bottom flask equipped with a stirrer. Octadecylamine (0.5 mole) was dissolved in 500 ml. dioxane and added to the thiourea/formaldehyde solution. The mixture was warmed slowly until it formed a waxy mass. It was cooled, filtered and extracted with methanol to afford the title compound as a white, fluffy material.
