We have developed a family of 4-benzimidazolyl-N-piperazinethyl-pyrimidin-2-amines that are subnanomolar inhibitors of Lck. A subset of these Lck inhibitors, with heterocyclic substituents at the benzimidazole C5, are also low-nanomolar inhibitors of cellular IL2 release. (C) 2009 Elsevier Ltd. All rights reserved.

Herein, we have developed a mild and selective reductive deprotection method for the MAc protected alcohols using sodiumborohydride. The new deprotection conditions provide a complete orthogonality between O-MAc and other protecting groups such as tert-butyl ester, N-Boc, Fmoc, Cbz, O-TBDMS, N-benzyl, O-benzyl, O-acetyl, N-acetyl, N-MAc, etc. In addition to O-MAc deprotection, this method is also
