PURPOSE:To obtain advantageously a radioactive compound using a nucleus seed with a short life, by presealing hermetically a given amount of an intermediate for the desired radioactive compound within a reactor, attaching the reactor to a device for synthesizing the radioactive compound in synthesis, carrying out synthetic reaction. CONSTITUTION:In synthesizing a radioactive compound using a nucleus seed with a short life, especially a radioactive drug such as <11>C-N-methylspiperone (dopamine receptor blocking agent) useful for diagnosis, examination, etc. with positron CT100, each of a given amount (necessary amount for one administration) of an intermediate (e.g., alkali salt of spiperone) for the compound together with an inert gas is presealed hermetically within the reactor 70, preserved, the reactor 70 is attached to the device 30 for synthesizing the radioactive compound in case of necessity, and the intermediate is reacted with <11>C-CH3I, etc., so that the desired compound is obtained stably and simply even if a radioactive substance is synthesized by introducing an unstable intermediate or an intermediate of complicated synthesis into a nucleus seed with a short life.
