実験手順
To a mixture of 5-chloro-2-nitropyridine (3 g, 18 mmol) in MeOH (20 mL), sodium methanethiolate (1.4 g, 20 mmol) was added at 0° C. and the mixture stirred at 20° C. for 2 hours. The resulting suspension was filtered and washed with water, and dried in vacuum to afford crude 117a as a yellow solid (2 g, 66%) without purification for next step. MS: [M+H]+ 171.
