Procedure

To a solution of (1R,2S)—N1-(6-(2,6-dichloro-3,5-dimethoxyphenyl)quinazolin-2-yl)cyclohexane-1,2-diamine (0.94 g, 2.1 mmol) in dichloromethane (25 mL) at 0° C. was added DIEA (0.37 mL, 2.1 mmol) and acryloyl chloride (0.17 mL, 2.1 mmol) and the reaction was stirred for 3 h. 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-dichloro-3,5-dimethoxyphenyl)quinazolin-2-yl)amino)cyclohexyl)acrylamide (0.8 g, 76%). MS (ES+) C25H26Cl2N4O3 requires: 500, found: 501.
