Reaction Steps

(2-Fluoropyridin-3-yl)methanol (508 mg, 3.998 mmol) was first treated with SOCl2 (1.5 ml) in CH2Cl2 (5 ml) at rt for 3 hrs. The solvent was removed to get a crude 3-(chloromethyl)-2-fluoropyridine. Then following General Procedure A, the title compound (910 mg, 85%) was prepared from 2-amino-4-chlorobenzenethiol (957 mg, 5.995 mmol), K2CO3 (2.7 g, 19.98 mmol) in DMF (20 ml).
