Product 1

HCID 1784935005-[6-(2,6-difluoro-3,5-dimethoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-N,N-dimethyl-2,3-dihydro-1-benzofuran-2-carboxamide

Procedure

This compound was prepared by using procedures analogous to those described for the synthesis of Example 4, Step 2 starting from 6-(2,6-difluoro-3,5-dimethoxyphenyl)-3-iodo-1H-pyrazolo[3,4-d]pyrimidine and N,N-dimethyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1-benzofuran-2-carboxamide (Peak II from chiral separation, Example 4, Step 1). LCMS (M+H)+=482.1. 1H NMR (300 MHz, DMSO-d6) δ: 14.25 (s, 1H), 9.77 (s, 1H), 8.01 (s, 1H), 7.91 (d, J=8.5 Hz, 1H), 7.18 (t, J=8.4 Hz, 1H), 6.97 (d, J=8.5 Hz, 1H), 5.83-5.70 (m, 1H), 3.94 (s, 6H), 3.55-3.49 (m, 2H), 3.13 (s, 3H), 2.90 (s, 3H).
