Procedure

A room temperature solution of Example 1C (2.36 g, 10.0 mmol) and cyclohexylamine (2.0 mL) in dioxane (5 mL) was stirred for 16 hours, diluted with ethyl acetate (100 mL), washed sequentially with 3M HCl (20 mL), water (20 mL) and brine (10 mL), dried (MgSO4), filtered, and concentrated to provide the desired product of sufficient purity for subsequent use.

Workup

  1. washwashed sequentially with 3M HCl (20 mL), water (20 mL) and brine (10 mL)
  2. dry with materialdried (MgSO4)
  3. filtrationfiltered
  4. concentrationconcentrated
