実験手順

Using analogous reagents and reaction conditions as described in Example 1 above, 4-amino-2-chloro pyridine (3.0 g, 23.33 mmol) in toluene (30 mL) was reacted with 1-chloro-2-isocyanatoethane (3.69 g, 35.0 mmol) and purified by column chromatography on silica gel (1.5% methanol in DCM) to afford 3.3 g of the product (61% yield).

後処理

  1. customreagents and reaction conditions
  2. custompurified by column chromatography on silica gel (1.5% methanol in DCM)
