YieldReaction ConditionsOperation in experiment
5.5 g With thionyl chloride; at 0℃; for 6h;Reflux; To a stirred solution of 4,5,6,7-tetrahydropyrazolo[l,5-a]pyridine-2-carboxylic acid (2-1) (5 g, 30.08 mmol) in MeOH (50 mL) was added SOCh (7.16 g, 60.18 mmol) at 0 C, and the mixture was stirred at reflux temperature for 6 h. The solvent was evaporated and co-distilled with MeOH and dried under high vacuum to afford semi-pure methyl 4,5,6,7-tetrahydropyrazolo[l,5-a]pyridine-2-carboxylate (2-2) (5.5 g, 30.52 mmol) as an off-white solid. This compound was used without further purification. MS (LCMS) m/z 181.13 [M+H]+.
