(6-(1-(Benzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido)pyridin-3-yl)(2-methoxyphenyl)methyl methanesulfonate (0.12 mmol) was dissolved in NMP (2 ml) following by addition of 2M solution of dimethylamine in THF (600 μl, 0.12 mmol) and DIEA (21 μl, 0.12 mmol). The reaction mixture was maintained at ambient temperature for 16 h. The resulting mixture was subjected to HPLC purification to provide the trifluoroacetic salt of target material (55 mg, 82%) as a colorless solid. 1H-NMR (DMSO): δ 8.43 (s, 1H), δ 8.40 (d, J=2 Hz, 1H), δ 8.06 (d, J=8.7 Hz, 1H), δ 7.96 (dd, J=2 Hz, J=8.7 Hz, 1H), δ 7.56 (bd, J=6.5 Hz, 1H), δ 7.39 (bt, J=6.5 Hz, 1H), δ 7.05-7.11 (m, 3H), δ 6.96 (s, 2H), δ 6.05 (s, 2H), δ 5.68 (bm, 1H), δ 3.85 (s, 3H), δ 2.75 (s, 6H), δ 1.42-1.45 (m, 2H), δ 1.13-1.16 (m, 2H).
