We present ALMA Cycle-0 observations of the CO (6-5) line emission and of the435um dust continuum emission in the central kpc of NGC 1614, a local luminousinfrared galaxy (LIRG) at a distance of 67.8 Mpc (1 arcsec = 329 pc). The COemission is well resolved by the ALMA beam (0".26 x 0".20) into acircum-nuclear ring, with an integrated flux of f_{CO(6-5)} = 898 (+-153) Jykm/s, which is 63(+-12)% of the total CO(6-5) flux measured by Herschel. Themolecular ring, located between 100pc < r < 350pc from the nucleus, looksclumpy and includes seven unresolved (or marginally resolved) knots with medianvelocity dispersion of 40 km/s. These knots are associated with strong starformation regions with \Sigma_{SFR} 100 M_\sun/yr/kpc^{2} and \Sigma_{Gas}1.0E4 M_\sun/pc^{2}. The non-detections of the nucleus in both the CO (6-5)line emission and the 435um continuum rule out, with relatively highconfidence, a Compton-thick AGN in NGC 1614. Comparisons with radio continuumemission show a strong deviation from an expected local correlation between\Sigma_{Gas} and \Sigma_{SFR}, indicating a breakdown of the Kennicutt-Schmidtlaw on the linear scale of 100 pc.
