By subjecting a compound represented by the formula (I) below to a reaction with methylamine, and if desired, to a protective group elimination process, there can be produced a high-purity [4-(3-aminophenyl)-6,7-dimethoxyquinazolin-2-yl]methylamine with high yield. (I) (In the formula, L represents a protective group of an amino group.)
