The process 
is studied in the center-of-mass energy range 1.17–2.00 GeV using data with an integrated luminosity of 201 pb
collected by the SND detector at the VEPP-2000 
collider. The cross section is measured for the first time. It is shown that the dominant mechanism of this reaction is the transition through the 
intermediate state. Our result on the cross section is consistent with the 
measurement in the 
mode. The search for radiative processes contributing to the cross section is performed, and no significant signal is observed.
