General procedure: These were made using NaHCO3 or 2,6-lutidine as detailed below, unless otherwise stated. Methylhydrazine sulfate (1.2 equiv) and NaHCO3 (5 equiv) were added to a solution of 3-formylpyrazolo[1,5-a]pyridine-5-carbonitrile (2) (1 equiv) in MeOH (5 mL). After all of the aldehyde was consumed, sulfonyl chloride or acyl chloride (1.3 equiv) was added and the reaction mixture stirred for a further 30 min. The solvent was removed in vacuo and the residue taken up in CH2Cl2 and water. The layers were separated and the aqueous phase extracted with CH2Cl2, then the combined organic layers were dried (Na2SO4) and the solvent removed in vacuo. Chromatography or trituration then afforded the hydrazides. Alternatively, methylhydrazine sulfate (1.2 equiv) and 2,6-lutidine (5 equiv) were added to a solution of 2 (1 equiv) in MeOH (5 mL). After all of the aldehyde was consumed, sulfonyl chloride or acyl chloride (1.3 equiv) was added and the reaction mixture stirred for a further 30 min. The hydrazide was then filtered off, washed with MeOH and dried.

The synthetic route of 1101120-05-1 has been constantly updated, and we look forward to future research findings.
