We consider the one-loop factorization of the simplest twist-3 process: inclusive deep-inelastic scattering of longitudinally polarized leptons on a transversely polarized nucleon target. By studying the Compton amplitudes for certain quark and gluon states at one loop, we find the coefficient functions for the nonsinglet twist-3 distributions in the factorization formula of g{sub 2}(x{sub B},Q{sup 2}). The result marks the first step towards a next-to-leading order formalism for this transverse-spin-dependent structure function of the nucleon.
