実験手順

A modification of the method described in Example 610 was used to couple tert-butyl 2-(4-amino-2-propyl-2H-pyrazolo[3,4-c]quinolin-1-yl)ethylcarbamate (2.08 g, 5.82 mmol) (Example 51, Parts A through G) with 3-[(tert-butoxycarbonyl)amino]pyridin-4-ylboronic acid (2.77 g, 11.6 mmol). After the first purification by IFC, 0.44 g of tert-butyl 2-(4-amino-2-propyl-2H-pyrazolo[3,4-c][1,7]naphthyridin-1-yl)ethylcarbamate was obtained as a yellow solid.
