Oracle Expdp issue: using where clause fails

hi, Oracle 12.1.0.2.PSU July 2017, failing on single table export with a where clause - this is on a Linux OUL6 server:

expdp  /

DUMPFILE=PF92PROD_EXPDP_SYSADM_PS_PV_ATT_DB_SRV.DMP

LOGFILE=PF92PROD_EXPDP_SYSADM_PS_PV_ATT_DB_SRV.LOG

TABLES="SYSADM.PS_PV_ATT_DB_SRV"

DIRECTORY=DATA_PUMP_DIR

CONTENT=ALL

METRICS=Y

QUERY=SYSADM.PS_PV_ATT_DB_SRV:"WHERE TO_CHAR( TRUNC( LASTUPDDTTM ), 'RRRR' ) = '2009'"              <**** this is the issue

Error:

LRM-00116: syntax error at ')' following 'LASTUPDDTTM'

I cannot seem to get this right! help

thanks, Steve
