In this article, we provide a detailed instruction for the synthesis of Compound X, including the preparation of the starting materials, the reaction conditions, and the purification protocol.
We also discuss the industrial applications of this compound and the challenges associated with its synthesis and use in industrial processes.

Preparation of Starting Materials:

The synthesis of Compound X requires several starting materials, including 2-methyl-4-fluoro-1H-benzimidazole (1a), 1,4-diiodomethane (2), sodium hydroxide (3), and tetrabutyl orthocarbonate (4).
These materials can be obtained from commercial suppliers or synthesized according to literature procedures (5, 6, 7).

Reaction Conditions:

The synthesis of Compound X involves a sequence of reactions, including the reaction between 2-methyl-4-fluoro-1H-benzimidazole (1a) and 1,4-diiodomethane (2) to form the intermediate 4-fluoro-2-(1-iodomethyl)-1H-benzimidazole (1b), followed by the reaction with sodium hydroxide (3) and tetrabutyl orthocarbonate (4) to form Compound X (see Scheme 1).

Scheme 1: Synthesis of Compound X

The reaction between 1a and 2 can be carried out in a solvent such as DMF or DME at an elevated temperature, such as 80°C to 100°C.
The reaction is typically complete within 2 to 3 hours.
The resulting intermediate 1b can be extracted with a solvent such as ethyl acetate, and the organic phase can be washed with aqueous sodium bicarbonate, sodium chloride, and dried with anhydrous sodium sulfate.
The organic layer can be concentrated under reduced pressure to obtain a crude oil, which can be purified by flash chromatography on a silica gel column using a solvent such as ethyl acetate
