Reaction Steps
A mixture of 2-(3-chloro-4-hydroxyphenyl)-7-morpholino-5H-pyrido[3,2-b]indole-4-carboxamide (120 mg, 0.284 mmol), 1-bromo-2-chloroethane (67 μL, 1.42 mmol) and K2CO3 (196 mg, 1.42 mmol) in DMF (4.8 mL) in a vial was heated at 40° C. for 3 h. Preparative HPLC (100×30 mm Luna C18 column, Solvent A=10% Methanol, 90% H2O, 0.1% TFA; Solvent B=90% Methanol, 10% H2O, 0.1% TFA; gradient of 0 to 100% B over 10 min at 42 mL/min) followed by SCX capture and release with 2 N NH3 in MeOH left 2-(3-chloro-4-(2-chloroethoxy)phenyl)-7-morpholino-5H-pyrido[3,2-b]indole-4-carboxamide (94 mg, 0.19 mmol, 68% yield) as a yellow solid.
