Methylamine → HCID 59835763, compound

Participants

Reaction Steps

80 mg (0.25 mmol) TBTU and 69 μL triethylamine are added to a solution of 112 mg (0.25 mmol) 5-[5-(4-chloro-phenyl)-pyridin-2-ylethynyl]-2-(2-pyrrolidin-1-yl-ethoxy)-benzoic acid (Example 22) in 5 mL DMF and the reaction mixture is stirred for 2 h at RT. Then 31 mg (1.0 mmol) methylamine are added and stirring is continued for a further 2 h at RT. The mixture is evaporated down i. vac., the residue is combined with dilute Na2CO3 solution, extracted exhaustively with DCM and the organic phase is dried over Na2SO4. After the desiccant and solvent have been eliminated the residue is purified by chromatography (silica gel, DCM to DCM/MeOH/NH3 7:3:0.3).
