Histidine-Boc deprotectection

A question on Fmoc-solid phase peptide synthesis (SPPS). Is Boc-protected Histidine too labile? Merck's [website](https://www.merckmillipore.com/JP/ja/product/Fmoc-HisBoc-OH.CHA,MDA_CHEM-852052?ReferrerURL=https%3A%2F%2Fwww.google.com%2F) shows Boc is labile to treatment with Piperidine. Anyone with such experience?
