Reaction Steps

Prepared using a procedure analogous to that described for Intermediate AE1 using (2S)-methyl 3-(2-(tert-butyldiphenylsilyloxy)ethoxy)-2-(1-(3-fluoro-2-methylphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yloxy)propanoate (Intermediate AF4) and 5-methylpyridin-2-amine. 1H NMR (400 MHz, DMSO) d 0.88 (9H, s), 1.96 (3H, d), 2.24 (3H, s), 3.75 (4H, m), 4.08-4.02 (1H, m), 4.14 (1H, m), 5.99 (1H, m), 7.50-7.29 (9H, m), 7.63-7.54 (5H, m), 7.89 (1H, d), 8.17 (1H, s), 8.51 (1H, s), 8.55 (1H, s), 10.94 (1H, s).
