They are rare in the 1-5µm region for historical reasons, but once available, high resolution atlases in this part of the spectrum will aid the study of a wide range of astrophysical phenomena. The aim of the CRIRES-POP project is to produce a high resolution near-infrared spectral library of stars across the H-R diagram. The aim of this paper is to present the fully reduced spectrum of the K giant 10 Leo that will form the basis of the first atlas within the CRIRES-POP library, to provide a full description of the data reduction processes involved, and to provide an update on the CRIRES-POP project. All CRIRES-POP targets were observed with almost 200 different observational settings of CRIRES on the ESO Very Large Telescope, resulting in a basically complete coverage of its spectral range as accessible from the ground. We reduced the 10 Leo spectra with the CRIRES pipeline, corrected the wavelength solution and removed telluric absorption with Molecfit, then resampled the spectra to a common wavelength scale, shifted to rest wavelengths, flux normalised, and median combined them into one final data product. We present the fully reduced, high resolution, near-infrared spectrum of 10 Leo. This is also the first complete spectrum from the CRIRES instrument. The spectrum is available online. The first CRIRES-POP spectrum has exceeded our quality expectations and will form the centre of a state-of-the-art stellar atlas. This first CRIRES-POP atlas will soon be available, and further atlases will follow. All CRIRES-POP data products will be freely and publicly available online. Description: The data presented is the fully reduced CRIRES-POP spectrum of the K giant 10 Leo. The spectrum covers the entire near-infrared as accessible to the ground, i.e. the Y, J, H, K, L, and M bands, and is split into five ascii files corresponding to the division of the photometric bandpasses by CRIRES: YJ, H, K, L, M. The spectrum is presented at R=90,000, at rest wavelengths in vacuum, having been corrected for telluric absorption, and normalised to the local pseudocontinuum. Some areas of residual telluric contamination have been masked, in the files the flux values of these areas have been replaced with '---'.
