Procedure

4-(6-(1-(Benzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido)pyridin-2-yl)benzene-1-sulfonyl chloride (˜35 μmol, 400 μl solution in chloroform) was treated with 2-methylpyrrolidine followed by the addition of DIEA (100 μl). The reaction mixture was kept at room temperature for 1 h, concentrated, then diluted with DMSO (400 μl). The resulting solution was subjected to HPLC purification. Fractions containing the desired material were combined and concentrated in vacuum centrifuge at 40° C. to provide the trifluoroacetic salt of target material (ESI-MS m/z calc. 505.0. found 505.9 (M+1), retention time 4.06 min) 1H NMR (250 MHz, DMSO-d6) δ 1.15 (m. 2H), δ 1.22 (d, 3H, J=6.3 Hz), δ 1.41-1.47 (m, 2H), δ 1.51 (m, 2H), δ 1.52-1.59 (m, 2H), δ 3.12 (m, 1H), δ 3.33 (m, 1H), δ 3.64 (m, 1H), δ 6.07 (s, 2H), δ 6.96-7.06 (m, 2H), δ 7.13 (d, 1H, J=1.3 Hz), δ 7.78 (d, 1H, J=8.2 Hz), δ 7.88 (d, 2H, J=8.5 Hz), δ 7.94 (t, 1H, J=8.2 Hz), δ 8.08 (d, 1H, J=8.2 Hz), δ 8.16 (d, 2H, J=8.5 Hz), δ 8.53 (s, 1H).
