Second, 2-aminothiazole-4-acetic acid can be protected by appropriate functional groups first, and then reacted with the active derivative of tert-butoxycarbonyl methoxylamine. For example, the carboxyl group of 2-aminothiazole-4-acetic acid is first converted into active esters, such as p-nitrophenyl ester, pentafluorophenyl ester, etc., and then reacted with tert-butoxycarbonyl methoxylamine under mild conditions. This strategy can improve the selectivity and yield of the reaction, and then the target product can be obtained through the deprotection step. The conditions for deprotection vary depending on the protecting group used. If it is a tert-butoxycarbonyl protecting group, it is often removed with acidic reagents such as trifluoroacetic acid.

(Z) - 2 - (tert-butoxycarbonyl methoxyimino-2- (2-aminothiazole-4-yl) -acetic acid must pay attention to many key matters during storage and transportation. The properties of this compound are quite special. The groups such as tert-butoxycarbonyl, methoxyimino and aminothiazole in its chemical structure make it sensitive to environmental factors.
During storage, the temperature is the first to be controlled. It should be placed in a cool place to prevent molecular structure changes due to excessive temperature, causing decomposition or deterioration. If the temperature is too high, tert-butoxycarbonyl may undergo a deprotection reaction, which may change the properties of the compound. It is also necessary to ensure that the storage environment is dry, because it is also quite sensitive to humidity. The intrusion of moisture may cause hydrolysis reactions, especially the acetic acid part, which is more susceptible to moisture and deterioration. At the same time, it is necessary to avoid contact with oxidants, reducing agents and acid and alkaline substances, because the functional groups contained in it are prone to chemical reactions with these substances and destroy the structure of the compound.
When transporting, the packaging must be solid and reliable. Appropriate packaging materials should be selected and properly wrapped to prevent the container from being damaged due to collision and vibration during transportation, which may lead to compound leakage. Moreover, it is necessary to strictly follow the relevant transportation regulations, clearly label its chemical properties and precautions, so that the transportation personnel are aware of its latent risk. The transportation environment should also be kept dry, cool and avoid direct sunlight. Only by paying such careful attention to the key points of storage and transportation can the quality and stability of (Z) - 2 - (tert-butoxycarbonyl methoxyimino - 2 - (2 - aminothiazole - 4 - yl) - acetic acid be ensured.
