Reaction Steps

A suspension of 5-cyclopent-1-en-1-yl-2-(3-methylquinoxalin-2-yl)-N-(tetrahydro-2H-pyran-4-yl)pyrazolo[1,5-a]pyrimidin-7-amine (30 mg, 0.0703 mmol) and palladium on carbon (5%, 30 mg) in dichloromethane (2.0 mL) and methanol (2.0 mL) was stirred for 3 h under hydrogen atmosphere. Then reaction mixture was filtrated with chloroform, and the filtrate was concentrated in vacuo. The crude was purified by silica gel column chromatography (hexane:ethyl acetate=19:1 to 1:1) to give 5-cyclopentyl-2-(3-methylquinoxalin-2-yl)-N-(tetrahydro-2H-pyran-4-yl)pyrazolo[1,5-a]pyrimidin-7-amine (the compound of Example 1.012 listed in the Table of Examples as described hereinafter). 1H-NMR (400 MHz, CDCl3): δ 1.67-1.95 (8H, m), 2.08-2.20 (4H, m), 3.05 (3H, s), 3.11-3.23 (1H, m), 3.60 (2H, ddd, J=11.8, 11.8, 2.4 Hz), 3.74-3.85 (1H, m), 4.10 (2H, ddd, J=11.5, 3.3, 3.3 Hz), 5.94 (1H, s), 6.32 (1H, d, J=7.9 Hz), 7.02 (1H, s), 7.71-7.79 (2H, m), 8.04-8.08 (1H, m), 8.16-8.20 (1H, m).
