Reaction Steps

The product from Example 1a (4.93 g, 0.025 mol) was dissolved in a mixture of EtOH (80 mL) and water (30 mL). To this was added hydroxylamine hydrochloride (8.6 g, 0.123 mol) and the resulting mixture heated to 100° C. for 8 h. The reaction mixture was poured into dilute sodium hydroxide solution and the crude product isolated by extraction with CH2Cl2 and dried over MgSO4 filtered and concentrated under vacuum giving the title compound. The material was used as isolated.
