Diisopropylethylamine → 2-methoxy-N-[1-methyl-2-phenyl-2-(1-pyridin-2-yl-1H-indazol-5-yloxy)-ethyl]acetamide

Participants

Reaction Steps

1-Methyl-2-phenyl-2-(1-pyridin-2-yl-1H-indazol-5-yloxy)-ethylamine (118a, 14 mg, 0.041 mmol), DIPEA (12 ul, 0.070 mmol) and acetonitrile (2 ml) were charged in a 7 ml vial. Methoxyacetyl chloride (12 ul, 0.13 mmol) was added, the vial was sealed and the solution stirred (magnetic bar) at r.t. for 1 h. Concentration and purification on C18 (Kromasil) with acetonitrile:water:TFA, 45:55:0.1 to 90:10:0.1 over 30 min, afforded 5 mg (29%) of 2-methoxy-N-[1-methyl-2-phenyl-2-(1-pyridin-2-yl-1H-indazol-5-yloxy)-ethyl]acetamide.
