Intermediate 4-(4-cyclopropylnaphthalen-1-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (45.0 g, 0.169 mol) and triethylamine (18.7 g, 0.183 mol) of were added into absolute ethanol (400 mL) at room temperature. Cooling to 0 °C, dropping 150 mL of absolute ethanol solution of ethyl bromoacetate (29.6 g, 0.18 mol), and controlling the temperature to 0 °C for 1 h after dropping. Most of the solvent was evaporated under reduced pressure, and the reaction solution was poured into 250 mL of water, extracted with dichloromethane (100 mL × 3), and the organic layers were combined. Wash with 200 mL water and 200 mL saturated sodium chloride solution, and dry the organic layer with anhydrous sodium sulfate. 52.4 g yellow oil product was obtained with a yield of 88.2 %.

2 Experimental details

All H atoms were included in calculated positions and refined as riding atoms, with C–H = 0.90–0.97 Å with U iso(H) = 1.5 U eq(C) for methyl H atoms and 1.2 U eq(C) for all other H atoms.

3 Comment

Lesinurad sodium is the first inhibitor of uric acid selective reabsorption transporter-1 (URAT1), which was first developed by Aread Biosciences and then continued to be developed by Astra Zeneca [5]. The chemical name of lesinurad sodium is 2-{[5-bromo-4-(4-cyclopropylnaphthalene-1-yl)-4h-1,2,4-triazol-3-yl]thio} acetic acid, which is mainly used for treating hyperuricemia related to gout in combination with xanthine oxidase inhibitors (such as allopurinol and febuxostat) [6], [7], [8]. Optimizing the synthesis process of lesinurad sodium and its derivatives has attracted the attention of researchers [9], [10], [11]. Recently, we have been focusing on the synthesis of esinurad sodium and optimizing its synthesis process. Here we reveal the synthesis and crystal structure of methyl 2-{[4-(4-cyclopropyl-1-naphthyl)-4H-1,2,4-triazole-3-yl]thio} acetate, the key intermediate of lesinurad sodium.

In the molecules of the title structure bond lengths and angles are very similar to those given in the literature [1215]. In the title structure, the dihedral angle formed by the naphthalene ring plane, the 1,2,4-triazole-3-thione plane and the cyclopropyl group plane are 54.6°, 71.5(73)° and 86.9°, respectively. These parameters are different from the data reported before [13]. The dihedral angle between the 1,2,4-triazole-3-thione plane and the ester plane to which it is connected is 89.0(213)°. The torsion angles of N2–C4–S1–C3 and C4–S1–C3–C2 are −12.798(207)° and 69.286(186)°. Intermolecular C–H⋯O hydrogen bonds and C–H⋯N hydrogen bonds connect two adjacent compounds into a dimer.
