Participants

Reaction Steps

The subtitled compound was prepared substantially in accordance with the method detailed in Example 24A using 6.0 g (0.030 mol) of N-(3-aminopropyl)pyrazole, 8.5 g of potassium carbonate and 2.65 g (O.013 mol) of o-nitrobenzoyl chloride with the exception that the final product was purified by crystallization from a cyanomethane/diethyl ether solution, followed by recrystallization from an ethanol/diethyl ether solution, to provide 6.62 g of the desired subtitled intermediate (m.p. 78°-81° C.).
