반응 단계
Oxalyl chloride (123 mL; 1.45 mmol), Intermediate 8 (120 mg; 0.48 mmol), 4-(aminosulfonyl)-N′-hydroxybenzenecarboximidamide, prepared as described in WO 2006/013104 A1 from 4-cyanobenzene-1-sulfonamide (ABCR; CD10716), (104 mg; 05 mmol, 1 eq.) and DIEA (250 mL; 1.45 mmol) were reacted according to the procedure described for Example 38. Purification by recrystallisation from DCM/n-pentane afforded the title compound as a white solid. LC/MS (Method A): 426.3 (M−H)−. HPLC (Method A) Rt 4.93 min (purity 89.2%).
