From the exact three-body distorted wave amplitude obtained by other authors for the one-charged-particle-transfer reaction A(x, y)B within the strict three-body (x = y + a and B = A + a, where a is a transferred particle) model, its part is separated in which the three-body Coulomb dynamics of the transfer mechanism is taken into account correctly. The contribution of the three-body Coulomb dynamics of the transfer mechanism to the partial wave amplitudes at l >> 1 for the peripheral proton-transfer reactions {sup 13}C({sup 3}He, d){sup 14}N, {sup 13}C({sup 14}N, {sup 13}C){sup 14}N, and {sup 9}Be({sup 10}B, {sup 9}Be){sup 10}B is estimated within the three-body approach combining the dispersion method and the DWBA approach. For these reactions, the Coulomb renormalization factors, arising owing to correctly taking into account the three-body Coulomb dynamics of the proton-transfer mechanism in the DWBA cross sections, are calculated. A new estimate is obtained for the values of the asymptotic normalization factors for p + {sup 13}C {sup {yields}} {sup 14}N, which also have astrophysical interest.
