CAS No.:1175008-62-4

Molecular Formula: C13H11NOS

Uses : Intermediate of herbicide trifloxysulfuron

Synthesis: 2-chloro-3-hydroxypyridine is treated with 1.0 equiv. of benzyl bromide in acetone to form 2-chloro-3-benzyyloxypyridine in 97% yield. 2-Chloro-3-benzyyloxypyridine then reacts with 1.2 equiv. of thiourea in anhydrous ethanol to produce 2-mercapto-3-benzyloxypyridine in 77.95% yield.

2-Chloro-3-(2, 2, 2-trifluoroethoxy)pyridine

Molecular Formula: C7H5ClF3NO

Uses : Fungicidal activity

Synthesis : Synthesized by the reaction of 2-chloro-3-hydroxypyridine with 2-chloro-1, 1, 1-trifluoroethane

2-Aminosulfonyl-3-(2, 2, 2-trifluoroethoxy)pyridine
