We present first results of a spectroscopic survey targeting K-selectedgalaxies at z=2.0-2.7 using the GNIRS instrument on Gemini-South. We obtainednear-infrared spectra with a wavelength coverage of 1.0-2.5 micron for 26K-bright galaxies (K<19.7) selected from the MUSYC survey using photometricredshifts. We successfully derived spectroscopic redshifts for all 26 galaxiesusing rest-frame optical emission lines or the redshifted Balmer/4000 Angstrombreak. Twenty galaxies have spectroscopic redshifts in the range 2.0
