Procedure
A solution of potassium 4-pyridinethiolate (20.00 g, 134 mmol) and 2-chloro-5-nitroanisole (20.91 g, 112 mmol) in dimethylformamide (80 mL) was stirred at room temperature for 24 hours. The reaction mixture was poured into ice water and a brown solid was collected by filtration. The solid was stirred with 3N HCl (400 mL) for 30 minutes, and the solution filtered. The filtrate was basified with ammonium hydroxide with cooling in an ice bath. Filtration of the basic solution yielded the title anisole as an orange solid (26.23 g, 90%); mp 133°-135° C. 1H-NMR (300 MHz, d6-DMSO): 3.95 (s, 3H, OCH3) 7.24 (dd, 2H, J=4.6, 1.7 Hz, aromatic) 7.53 (d, 1H, J=8.3 Hz, aromatic) 7.88 (dd, 2H, J=8.3, 2.3 Hz, aromatics) 8.48 (dd, 2H, J=4.7, 1.3 Hz, aromatic). MS (CI, CH4): 263 (M+1).
