To a suspension of 2-(6-methyl-5-nitro-pyridin-2-ylsulfanyl)-ethanol (323 mg, 1.5 mmol) and 7 ml of acetic acid, zinc dust (220 mg, 3.4 mmol) was added at 0° C. The mixture was stirred at room temperature for 2 hr. Zinc dust was filtered through celite and the residue was purified by HPLC to provide 2-(5-amino-6-methyl-pyridin-2-ylsulfanyl)-ethanol as an oil (93 mg, 33%). 1HNMR (DMSO-d4, 400 MHz) δ 1.91 (s, 1H), 2.38 (s, 3H), 2.50-2.51 (m, 2H), 3.12-3.15 (m, 2H), 3.57-3.61 (m, 2H), 7.26-7.28 (m, 1H), 734-7.36 (m, 1H). Exact mass calculated for C8H12N2OS 184.07 found 184.9 (MH+).
