Reaction Steps

Compound 1 (500 mg, 1.44 mmol) and hydrazine (4 ml) were put in a pressure tube. Ethanol (30 ml) was added. The pressure tube was flushed with argon, sealed and stirred at 100-160° C. for 10-16 h. After cooling, the resulting solid was collected and washed with methanol and ether to give compound 138 (40 mg). The product was used in the next step without further purification.
