Definitions
- Fezolinetant (generic name) (VEOZAH®) was developed as a selective antagonist of the NK-3 receptor and is particularly useful as a compound for the treatment and/or prevention of sex hormone-dependent disorders (e.g., moderate to severe vasomotor symptoms associated with menopause, such as hot flashes and flushes).
- Fezolinetant is (R)-(4-fluorophenyl)-(8-methyl-3-(3-methyl-1,2,4-thiadiazol-5-yl)-5,6-dihydro-[1,2,4]triazolo[4,3-a]pyrazin-7(8H)-yl)methanone and is described in US Pat. No. 5,999,366.

- R1 represents methyl or methyl-d3.
- Patent document 3 describes the non-deuterated intermediate, 3-methyl-1,2,4-thiadiazole-5-carbohydrazide (2n):

- a synthetic method has been disclosed in which a compound represented by the formula (II-1-b) or its salt is obtained and passed through the process.
- the yield of the alkoxycarbonylation reaction by lithium exchange reaction is low at 29%, and the alkoxycarbonylation reaction by carbon monoxide insertion reaction in the presence of a metal catalyst can obtain the compound represented by the formula (II-1-b) in good yield, but requires the use of toxic carbon monoxide gas and has limitations on scale-up, etc., so there remain issues in practical application.

- the object of the present invention is to provide a safe, high-yield, and practical method for producing a compound represented by the formula (I) or a salt thereof.
