反応手順
A mixture of (1R,2S)—N1-(6-(2,6-difluoro-3-methoxyphenyl)quinazolin-2-yl)cyclopentane-1,2-diamine (0.045 mmol), propiolic acid (0.004 mL, 0.067 mmol), HATU (25 mg, 0.067 mmol) and DIEA (0.023 mL, 0.135 mmol) in dichloromethane (1 mL) was stirred at room temperature for 60 minutes. LC-MS indicated complete consumption of SM. The reaction mixture was purified by silica gel chromatography to yield N-((1S,2R)-2-((6-(2,6-difluoro-3-methoxyphenyl)quinazolin-2-yl)amino)cyclopentyl)propiolamide (Compound 2) (13 mg, 68%). MS (ES+) C27H27N5O3 requires: 422, found: 423 [M+H]+.
