Komponenten

Versuchsvorschrift

A mixture containing 6 g (0.025 mole) of 2-phenyl-4-chloroquinazoline, 3,53 g (0.035 mole) of 4-hydroxypiperidine and 100 ml of 95% ethyl alcohol was refluxed for 3 hrs. One gram of sodium hydroxide (in one ml of water) was added and the mixture was refluxed for an additional 2 hr period. The mixture was filtered and the filtrate was added to 300 ml of water. The white crystalline precipitate was separated and recrystallized with methanol and water to give 3.2 g of the title compound, m.p. 165°-167° C.
