| titleOfInvention | Method for producing orotic acid derivative |
| abstract | Provided is a method for producing an orotic acid derivative, the method comprising a condensation step of performing, under a basic condition, a condensation reaction between an orotic acid halide represented by General Formula (I) and a compound represented by General Formula (II) to generate an orotic acid derivative represented by General Formula (III); and a neutralization crystallization step of precipitating crystals of orotic acid by neutralization crystallization to separate a liquid containing the orotic acid derivative from the crystals of orotic acid, after the condensation step. In General Formula (I), (II), or (III), X is a halogen atom, and A is a group represented by General Formula (A-1) or (A-2). In General Formula (A-1) or (A-2), R1 is a hydrogen atom or an organic group, and R2 and R3 are each independently an organic group. In a case where R1 is an organic group, R1 and R2 may be bonded to each other to form a ring. |
