We setup a bootstrap approach to compute the first stringy correction to the supergravity regime of the correlation function of five $20'$ operators in $\mathcal{ N}=4$ super Yang-Mills. We use factorization of Mellin amplitudes and supersymmetric constraints to fix almost completely our ansatz. The two last coefficients are fixed by a justified mild assumption based on the flat-space limit of the Mellin amplitude. As a byproduct of our analysis, we also compute the first stringy correction to the four-point correlators of three $20'$ operators and either one R-symmetry current or one stress tensor.
