实验步骤: Isopropyl N-cyano-4-pyridinecarboximidate (0.50 g, 2.6 mmol) was dissolved in methanol (5 ml), and 2-phenylthioethylamine (0.49 g, 3.2 mmol) was added. The mixture was stirred at room temperature for 2 hours. After the reaction was completed, the reaction solution was concentrated under reduced pressure, and the residual concentrate was subjected to chromatography on a silica gel column (WAKO GEL C-200, 10 g) eluting with chloroform-methanol (50:1). The eluted fractions were concentrated under reduced pressure and crystallized from diethyl ether to give the title compound (0.49 g, 1.7 the reaction solution was concentrated under reduced pressure the residual concentrate eluting with chloroform-methanol (50:1) The eluted fractions were concentrated under reduced pressure crystallized from diethyl ether

实验步骤: Mix 2-aminoethanethiol hydrochloride (4.07 g, 35.6 mmol) in dioxane (75 mL) at 50° C. Add sodium hydride (60% in mineral oil, 2.84 g, 71.0 mmol) at room temperature under nitrogen. Stir the reaction for 5 minutes. Add 2-chloropyridine (3.5 mL, 37 mmol) to the mixture. Reflux the mixture for 24 hours, and then cool to room temperature. Add water (100 mL), and methylene chloride (300 mL) to this mixture. Extract the aqueous layer with methylene chloride (3×50 mL). Wash the combined organic phase with brine (200 mL), dry (magnesium sulfate), filter and concentrate to an orange oil. Perform flash chromatography on silica gel eluting with 50% (80:18:12 CHCl3/MeOH/concentrated NH4OH)/methylene chloride to afford the title compound as a yellow oil (1.67 g) m/e=155 (MH+). at room temperature the reaction for 5 minutes Reflux the mixture for 24 hours Extract the aqueous layer with methylene chloride (3×50 mL) Wash the combined organic phase with brine (200 mL) dry (magnesium sulfate) filter concentrate to an orange oil
