Reaction Conditions:
in xylene; for 12 h;Heating / reflux;
Steps:
1; A
A mixture of a-l (0.166 mol) and urea (0.199 mol) in xylene (300 ml) was stirred under reflux for 12 hours. The reaction was cooled down to room temperature. The precipitate was filtered off, rinsed with xylene and diisopropyl ether, and then dried, yielding 32g of intermediate a-2 (93%, melting point: > 260°C).
