How can I change data in pandas dataframe by condition?

I need convert pandas dataframe.

I have dataframe:

data10SGD01|AA169|10SGD01|AA170

I need to get:

data10SGD01AA169|10SGD01AA170

I try:

df['data'] = df['data'].str.replace('|(?=AA)', '', regex=True)

This regex does not work. Where is the mistake?

Version of pandas == 2.0.3
