Conditions
- Temperature
- 160 °C
Procedure
The compound prepared in Example 31 (7.0 g, 0.018 mol), paraformaldehyde (0.29 g, 0.0093 mol) and di-n-butylamine (2.43 g, 0.0186 mol) are charged to a reaction and which is then sealed. The temperature is increased to 160° C. and held there for four hours. The reaction mass is cooled to 110° C. at which time sodium methoxide (0.16 g, 0.0028 mol) is added. The reaction mixture is then heated to 205° C. and held there for three hours. The reaction mass is then cooled to 110° C. and 100 mL of xylenes are added. The reaction mass is neutralized with 10% aqueous hydrochloric acid and the organic phase is twice washed with water. Xylene is then distilled off and replaced with heptane. After cooling the heptane solution, yellow crystals separate out and are isolated by filtration. After drying to constant weight, the title compound (5 g) is obtained as a solid melting at 178° C.
