実験手順

Triethylamine (0.425 mL, 3.05 mmol) was added to a 0° C. solution of (3-{[(3-benzyl-5-chloro-4-oxo-3,4-dihydro-pyrrolo[2,1-f][1,2,4]triazin-2-yl)-cyclopropyl-methyl]-amino}-propyl)-carbamic acid tert-butyl ester (0.74 g, 1.52 mmol) and 4-methylbenzoyl chloride (0.403 mL, 3.05 mmol) in CH2Cl2 (10 mL) and was stirred at 0° for 1.5 h. The reaction mixture was quenched with 1 N HCl (30 mL) and extracted with CHCl3 (3×50 mL). The combined organic extracts were washed with saturated NaHCO3 (1×100 mL), dried (Na2SO4), filtered and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel eluting with 3/1 hexane/EtOAc to afford the title compound (0.90 g, 98%) as a solid: MS (ESI+) 604 (M++H); HRMS (ESI+) calculated: 604.2691 (M++H). found: 604.2702 (M++H).
