The invention discloses a 2 - methoxy - 6 - methoxybenzene and thiazole preparation method, which belongs to the field of chemical synthesis, the method the 2 - amino - 6 - methoxybenzene and thiazole dissolved in organic solvent, adding hydrochloric acid solution, dropping sodium nitrite solution, reaction finishes, adding hydrochloric acid solution containing the catalyst, cooling, recrystallized to obtain the intermediate product, the intermediate product add methanol, sodium methoxide, under the protection of nitrogen, heating the reaction, after the reaction, natural cooling to room temperature, filter, be insoluble, water heating, freezing, filtering, vacuum drying to obtain the 2 - methoxy - 6 - methoxybenzene and thiazole. The invention selects the synthetic route of the few steps, the reaction route is short, controllability of the strong, few by-products, high yield, low cost at the same time, less wastes, high content of the target products, high purity, it is suitable for industrial production.
