We have observed the region centered on the hard X-ray transient EXS 1727.9-2952 near the Galactic Centre using the Narrow Field Instruments (NFI) of the BeppoSAX X-ray satellite. The soft X-ray intensity distribution in the full field of the MECS instruments revealed the existence of 10 sources. Three of them are within the 10' error circle of the EXS 1737.9-2952 nominal position. With a 3' flux collection radius, the individual background-subtracted source count rates were 0.0069-0.0162cts/s with the MECS 2 and 3 data combined, indicating source flux densities of the order 10^–12erg/cm²/s (1.65-10.5keV). The non-detections in LECS observations indicate that the sources are very weak in the 0.1-2keV energy range. The locations of the new sources overlap partly with that of the CO molecular cloud observed by us with the SEST telescope at ESO. A few of the new sources are close to the VLA radio sources previously found inside the EXITE error circle of the EXS position, but none of them coincide.
