Ta. Kelly et Dw. Mcneil, A SIMPLE METHOD FOR THE PROTECTION OF ARYL AMINES AS THEIR T-BUTYLCARBAMOYL (BOC) DERIVATIVES, Tetrahedron letters, 35(48), 1994, pp. 9003-9006
It has been found that aryl amines can be directly protected as their
Boc derivatives by treatment of the amine with two equivalents of NaHM
DS in THF followed by one equivalent of di-t-butyldicarbonate. This pr
ocedure works on a wide variety of both electron-rich and electron-def
icient aryl amines.
