2*Anilinoethanol

Anilinoethanol, Azido—, C,H,bN O and Diazido—. C HfUtO Derivatives were not found in Beil or CA through 1956... 

Hydroxyethylaminobenzene or 0-Hydroxy-ethylaniline. See under 2-Anilinoethanol and Derivatives in Vol 1, pp A424-31. This includes Pentryl (Trinitroanilinoethanol Nitrate) various halogen derivs of anilinoethanol... 

When bis(2-anilinoethyl) phenylphosphonite [PhP(OCH2CH2NHPh)2] (from 2,3-diphenyl-1,3,2-oxazaphospholidine with 2-anilinoethanol) was heated at 200° for Ihour it gave 1,4-diphenylpiperazine (1660). The reaction of p-substituted A -sulfinylanilines (130) with styrene oxide in the presence of tetraethylammonium bromide produced the corresponding 1,2,4,5- (131) and 1,2,4,6-tetraarylpiperazines, whose configurations have been established on the basis of the n.m.r. spectral studies (1661). Heating of A7-sulfinylaniline (130, R = H) with ethylene carbonate (132) and lithium bromide at 140° for 6 hours gave 50% 1,4-diphenylpiperazine (1662).

POGlg added portionwise to a soln. of 2-anilinoethanol hydrochloride in ice-cold chloroform, while it is gradually heated to 84 during 3 hrs., and allowed to stand overnight at room temp. N-(2-chlorethyl) aniline hydrochloride. Y 99.5%.—Hydrochlorides of compounds like the above are more readily chlorinated than the free bases. R. S. Tipson, J. Org. Ghem. 27, 1449 (1962).
