A mixture of 4-(2-(((1R,2S)-2-((tert-butoxycarbonyl)amino)cyclopentyl)amino)quinazolin-6-yl)-3-methoxybenzoic acid (57 mg, 0.12 mmol), cyclopropyl amine (0.012 mL, 0.18 mmol), HATU (68 mg, 0.18 mmol) and DIEA (0.052 mL, 0.30 mmol) in dichloromethane (1.5 mL) was stirred at room temperature for 30 minutes. LC-MS indicated complete consumption of SM. The reaction mixture was purified by silica gel chromatography to yield tert-butyl ((1S,2R)-2-((6-(4-(cyclopropylcarbamoyl)-2-methoxyphenyl)quinazolin-2-yl)amino)cyclopentyl)carbamate (58 mg, 93%). MS (ES+) C29H35N5O4 requires: 517, found: 518 [M+H]+.
