실험 절차

Benzyl 1-isopropylspiro[chromeno[4,3-c]pyrazole-4,4′-piperidine]-1′-carboxylate (1.1 g, 2.6 mmol) was stirred in methanol (14.4 mL) with Pd/C (140.3 mg, 0.1318 mmol) under a balloon of hydrogen for 16 h. The reaction was filtered through a syringe filter and the solvent evaporated to give 1-isopropylspiro[chromeno[4,3-c]pyrazole-4,4′-piperidine] (750 mg, 100%). ESI-MS m/z calc. 283.2. found 284.3 (M+1)+; Retention time: 1.01 minutes (3 min run).
