A process for producing a triazine derivative of the formula (III), ##STR1## wherein R 1 is a C 1 -C 4 alkyl group, n is an integer of O to 2, R 2 is hydrogen or a C 1 -C 2 alkyl group, and X is a halogen atom, n which comprises reacting a biguanide derivative of the formula, ##STR2## wherein R 1 and n are as defined in the formula (III), and X' is a halogen atom, n with a halocarboxylic acid ester of the formula, ##STR3## wherein R 2 and X are as defined in the formula (III), and R 3 is a C 1 -C 4 alkyl group, n in the presence of a base, wherein a dehydrating agent is present in the reaction system, and processes for producing 2-fluoroisobutyric acid ester as an intermediate compound for the production of the triazine derivative. |
