실험 절차

To a solution of 7-(2-aminophenyl)-2-(4-hydroxyphenyl)-4,5,6,7-tetrahydro pyrazolo[1,5-a]pyrimidine-3-carbonitrile (33 mg, 0.1 mmol) in THF (5 mL) was added PPh3 (78.6 mg, 0.25 mmol) and tetrahydro-2H-pyran-4-ol (10 mg, 0.1 mmol). Then, DIAD (51 mg, 0.25 mmol) was added dropwise to the mixture at 0° C. and stirred at 0° C. for 10 min under N2. The mixture was allowed to warm to it and stirred at RT for 16 hr. The mixture was concentrated in vacuum and partitioned between DCM (20 mL) and brine (20 mL). Organic layer was separated from aqueous layers, dried over sodium sulfate and purified by Pre-TLC (DCM/CH3OH=10/1) to afford 5 mg (12%) of 7-(2-aminophenyl)-2-(4-(tetrahydro-2H-pyran-4-yloxy)phenyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine-3-carbonitrile as a colorless oil. 1H NMR (400 MHz, DMSO-d6) δ 7.70 (d, J=8.4 Hz, 2H), 7.66-7.58 (m, 2H), 7.58-7.52 (m, 1H), 7.03 (d, J=8.4 Hz, 2H), 6.97 (t, J=7.6 Hz, 1H), 6.69 (d, J=8.0 Hz, 1H), 6.49 (t, J=7.6 Hz, 1H), 6.23 (d, J=8.0 Hz, 1H), 5.63 (s, 1H), 5.21 (s, 2H), 4.66-4.56 (m, 1H), 3.90-3.79 (m, 2H), 3.54-3.43 (m, 2H), 3.25-3.18 (m, 1H), 2.97-2.86 (m, 1H), 2.21-2.07 (m, 2H), 2.02-1.92 (m, 2H), 1.65-1.50 (m, 2H). MS (ESI) m/e [M+1]+ 415.9.
