Formation of the N-benzyloxy amide link is very sensitive to steric hindrance and generally requires strong acylating systems such as HATU {N-[(dimethylamino)-1H-1,2,3-triazolo[4,5-b]pyridin-1-ylmethylene]-N- methylmethanaminium hexafluorophosphate} see: (a) Akiyama, M.; Iesaki, K.; Katoh, A.; Shimizu, K.

3 in a NMR tube with 3 equiv of pyridine indicates that with 0.7 equiv of TMSCl two exchanging products are first visible. After the addition of an excess TMSCl (up to 2.2 equiv), only one product remains. This is in agreement with previous findings (see ref. 20a).
