The amount of base used in the reaction is approximately equimolar to the starting compound 1-(2-dimethylaminoethyl)-5-mercapto-1H-tetrazole. Although the reaction temperature is not particularly limited, it is usually carried out at room temperature to about 40 to 60°C. The reaction time varies depending on the type of solvent used, reaction temperature, etc.30
It takes about 3 minutes to 3 hours. In these reactions, if the target compound [] or its salt is contaminated with Δ 2 -isomer,
If necessary, methods known per se may be used, such as Journal of Medicinal Chemistry, Vol. 18, 986.
(1975) to convert the compound [ ] or its It can be made into salt. When the resulting compound [] is obtained in free form, it is dissolved in an inert solvent such as dichloromethane or chloroform, and the compound []
A salt of the target compound [ ] can be made by reacting with an acid in an amount of about 1 to 10 times the molar amount. When the compound [] or a salt thereof is obtained in a racemic form, it can be isolated as an optically active form (D-isomer, L-isomer) by performing optical resolution by means known per se. The compound [] or its salt obtained in this way can be obtained by means known per se.
For example, it can be isolated and purified by solvent extraction, liquid conversion, dissolution, crystallization, recrystallization, chromatography, etc. The starting compound [] is produced by means known per se (for example, the method described in JP-A-49-289).
Further, the compound [] can be produced, for example, by the method shown in the following scheme. [In the above formula, R 1 and R 2 have the same meanings as above]. The starting compound chloroformate [ ] in the first step of the reaction in the above scheme is produced by a method known per se (for example, the method described in JP-A-57-9744). Furthermore, the compound [] has the general formula, R 1 CHO
It is produced by reacting an aldehyde represented by (the symbols in the formula have the same meanings as above) with phosgene in the presence of a catalyst (phosgenation reaction). Examples of the catalyst used here include tertiary amines such as N,N-dimethylaniline, N,N-dimethylaminopyridine, and pyridine, aromatic monoazines such as imidazole, substituted amides such as DMF,
Tetra-lower alkyl (1 to 4 carbon atoms) urea or thiourea such as tetrabutylurea, tetramethylurea, tetrabutylthiourea, and tetramethylthiourea, aliphatic tertiary phosphines such as trioctylphosphine, substituted phosphoramides such as HMPA etc. are used. The aldehyde as a raw material compound is used in an approximately equimolar amount to phosgene. The amount of catalyst used can be 0.01 to 0.1 times the molar amount of the aldehyde as the raw material. This phosgenation reaction is usually carried out in a solvent inert to the reaction. Suitable solvents include halogenated hydrocarbons such as carbon tetrachloride, chloroform and methylene chloride, aromatic hydrocarbons such as toluene and benzene, and aliphatic hydrocarbons such as hexane. Generally, this phosgenation reaction is carried out under atmospheric pressure, but if the raw material aldehyde is volatile,
The reaction can also be carried out at a pressure slightly higher than atmospheric pressure. The reaction temperature varies depending on the type of melting medium and the amount used, but is usually about -40°C to 100°C. The reaction time is about 30 minutes to 5 hours. After completion of this phosgenation reaction, the produced compound [] can be isolated and purified by concentration, distillation, etc. under atmospheric pressure or reduced pressure. A compound in which X represents iodine in the general formula [], that is, an iodoalkyl carbonate, can be obtained by reacting the compound [] with the compound [XI] in the presence of a base (first step reaction), and then reacting the resulting compound with sodium iodide. (second stage reaction). In the first step of the reaction, the starting compound []
is used in an approximately equimolar amount to compound [XI].
This reaction can usually be carried out in a solvent. Suitable solvents include those inert to the reaction, such as dichloromethane, chloroform, diethyl ether, and ethyl acetate. Examples of the base used in the reaction include organic tertiary amines such as pyridine, lutidine, triethylamine, and diisopropylethylamine. The amount of base used is approximately equimolar to the compound []. The reaction starts from −80
Proceed at 40°C. The reaction time varies depending on the reaction temperature, but is usually about 30 minutes to several days. After the first stage reaction is completed, the chloroalkyl carbonate obtained by washing the reaction solution with water, extraction, concentration, distillation, column treatment, etc. is reacted with sodium iodide to obtain iodoalkyl carbonate (stage 2). stage reaction). In the second stage reaction, the amount of sodium iodide used may range from equimolar to about 10 times the molar amount of the chloroalkyl carbonate. This second step reaction consists of acetone, acetonitrile, DMF, and DMSO.
It is carried out in the presence of a general-purpose solvent such as The reaction temperature runs from about room temperature to 70°C. The reaction time is usually about 15 minutes to 24 hours.
