HCID 11750854(RS)-N-(3-amino-benzo[d]isoxazol-6-ylmethyl)-2-ethoxy-2-(2-oxo-3-phenylamino-2H-pyridin-1-yl)-acetamide

Procedure

Using similar procedures as described in example 25, (RS)-ethoxy-(2-oxo-3-phenylamino-2H-pyridin-1-yl)-acetic acid ethyl ester (example 21.1) was hydrolyzed according to general procedure B. The corresponding acid was reacted according to general procedure C with 6-aminomethyl-benzo[d]isoxazol-3-ylamine (CAS 368426-78-2) to give (RS)-N-(3-amino-benzo[d]isoxazol-6-ylmethyl)-2-ethoxy-2-(2-oxo-3-phenylamino-2H-pyridin-1-yl)-acetamide. Light green powder. MS 434.2 ([M+H]+)
