2-[(l S2S)-l-Ethyl-2-benzyloxypropyl]-2,4-dihydro-4-[4-[4-(4-hydroxyphenyl)-l- piperozinyl] phenyl]-3H-l,2,4-triazol-3-one (1 kg) was added to the flask along with Dimethylsulfoxide (8 lit) at room temperature and stirred for 15 min. Solution of Sodium hydroxide (0.15 kg) in Water (0.3 lit) was added at same temperature and maintained for 1 hr. ((3S,5R)-5-((lH-l,2,4-triazol-l-yl) methyl)-5-(2,4- difluorophenyl)-tetrahydrofuran-3-yl)methyl-4-chlorobenzene sulfonate (1.2 kg) was added and maintained for 4-5 hrs. Water (10 lit) was added to the reaction mixture and stirred for 15 min. Ethyl acetate (7.5 lit) was added and stirred for 15 min. Aqueous layer and Ethyl acetate layer were separated and aqueous layer was extracted with Ethyl acetate (3 lit). Aqueous layer and Ethyl acetate layer were separated and total aqueous layer was washed with Water (5 lit) and stirred for 15 min. Aqueous layer and Ethyl acetate layer were separated and aqueous layer was washed with brine solution and stirred for 15 min. Aqueous layer and Ethyl acetate layer were separated and Ethyl acetate layer was dried with Sodium sulfate and distilled under vacuum at below 50C. The resultant crude was treated with Isopropyl alcohol (10 lit) and heated to 75-80C, maintained for material dissolved and charged with activated Carbon (0.05 kg) and maintained for 1 hr. The material was filtered through the Hyflow bed and washed with Isopropyl alcohol (1 lit). The resultant mass was cooled to room temperature, maintained for 2 hrs, filtered the solid and washed with Isopropyl alcohol (1 lit).Yield: 1.28Kg; HPLC: 98%

The synthetic route of 184177-83-1 has been constantly updated, and we look forward to future research findings.
