Procedure

Et3N (170 μL, 1.2 mmol) was added to a mixture of 2-(1-methylspiro[chromeno[4,3-c]pyrazole-4,4′-piperidine]-1′-carbonyl)benzoic acid (100 mg, 0.25 mmol), N-methylmethanamine hydrochloride (30 mg, 0.37 mmol), EDCI (48 mg, 0.25 mmol), and CH2Cl2 (1.5 mL) at ambient temperature. The mixture was allowed to stir for 16 h before it was diluted with CH2Cl2 and was washed with 1N HCl. The layers were separated and the organic layer was washed with 1N NaOH, and then brine before it was dried over sodium sulfate and was concentrated in vacuo to give N,N-dimethyl-2-(1-methylspiro[chromeno[4,3-c]pyrazole-4,4′-piperidine]-1′-carbonyl)benzamide (38 mg) as a white solid. ESI-MS m/z calc. 430.2. found 431.3 (M+1)+; Retention time: 2.24 minutes (3 min run). 1H NMR (400 MHz, CDCl3) δ 7.56 (d, J=7.7 Hz, 1H), 7.45-7.37 (m, 3H), 7.46-7.22 (m, 2H), 7.30-7.21 (m, 1H), 7.13-7.00 (m, 2H), 4.52 (d, J=13.5 Hz, 1H), 4.19 (s, 3H), 3.74-3.51 (m, 2H), 3.31 (t, J=11.9 Hz, 1H), 3.09 (s, 3H), 2.94 (s, 3H), 2.24-2.02 (m, J=13.9 Hz, 2H), 2.02-1.76 (m, 2H). N-isopropyl-4-(1-methyl-1H-spiro[chromeno[4,3-c]pyrazole-4,4′-piperidine]-1′-ylcarbonyl)benzamide was synthesized from 4-(1-methyl-1H-spiro[chromeno[4,3-c]pyrazole-4,4′-piperidine]-1′-ylcarbonyl)benzoic acid using the procedures described above.
