Reaction Steps

To a solution of 1-[2-(3-methylquinoxalin-2-yl)-7-(tetrahydro-2H-pyran-4-ylamino)pyrazolo[1,5-a]pyrimidin-5-yl]pyrrolidin-3-ol (200 mg, 0.449 mmol) and methanesulfonyl chloride (77 mg, 0.673 mmol) in dichloromethane (5.0 mL) was added triethylamine (0.125 mL, 0.898 mmol) at 0° C. After being stirred for 2 h, the reaction mixture was poured into water. The mixture was extracted with chloroform, and the organic layer was washed with saturated brine, dried over sodium sulfate, filtrated and concentrated in vacuo. The crude was purified by silica gel column chromatography (chloroform to chloroform:methanol=97:3) to give (3S)-1-[2-(3-methylquinoxalin-2-yl)-7-(tetrahydro-2H-pyran-4-ylamino)pyrazolo[1,5-a]pyrimidin-5-yl]pyrrolidin-3-yl methanesulfonate (the compound of Example 1.008 listed in the Table of Examples as described hereinafter). 1H-NMR (400 MHz, CDCl3): δ 1.73-1.83 (2H, m), 2.12-2.15 (2H, m), 2.30-2.39 (1H, m), 2.47-2.52 (1H, m), 3.04 (3H, s), 3.08 (3H, s), 3.56-3.63 (2H, m), 3.68-3.89 (4H, m), 3.99-4.02 (1H, m), 4.07-4.10 (2H, m), 5.19 (1H, s), 5.44-5.46 (1H, m), 6.20 (1H, d, J=8.2 Hz), 6.67 (1H, s), 7.70-7.77 (2H, m), 8.03-8.06 (1H, m), 8.16-8.19 (1H, m).
