Participants

Reaction Steps

A mixture of Example 1B (0.150 g, 0.442 mmol) and formohydrazide (0.066 g, 1.11 mmol) in acetonitrile (7 mL) was heated at 150° C. for 15 minutes in a Biotage microwave reactor. The solid was filtered. The filtrate was concentrated, treated with saturated aqueous NaHCO3 and extracted with ethyl acetate (2×). The combined organic layers were dried over MgSO4, filtered, concentrated, and purified on a 12 g column using the ISCO Companion flash system eluting with CH2Cl2/ethyl acetate (3:7 to 2:8) to provide the title compound.
