A mixture of compound 2 (9.0 g, 0.034 mol) and phenyl allyl ether (6.98 ml, 0.051 mol) in 200 ml of toluene is refluxed for 48 hours, cooled and evaporated under vacuum. The semisolid that remained (7.30 g, 54%) is crystallized from ether and recrystallized from ethyl acetate to give tan crystals. Yield: 2.4 g (18%); m.p. 176°-178° C. (Found: C, 74.96; H, 6.41; N, 10.40. C25H25N3O2 requires: C, 75.16; H, 6.31; N, 10.52).
