Participants

Reaction Steps

A mixture of (2R,4S)-4-[4-(6-amino-5-benzothiazol-2-ylpyridin-3-yl)-pyrazol-1-yl]-pyrrolidine-2-carboxylic acid (10.00 mg, 0.019 mmol), dimethylamine (0.009 g, 0.2 mmol), TBTU (12.4 mg, 0.0388 mmol), and DMF (1 mL) was charged with DIPEA (0.03 mL, 0.2 mmol) and allowed to stir at rt for 10 min. The solution was used directly for HPLC purification. The fractions containing the pure product were concentrated in vacuo to afford the title compound as a yellow solid. 1H NMR (400 MHz, CD3OD): δ=2.40-2.51 (m, 1H), 2.87 (d, J=6.1 Hz, 1H), 3.04 (s, 3H), 3.09 (s, 3H), 3.72 (br. s., 1H), 3.85 (dd, J=12.5, 6.4 Hz, 1H), 5.02 (t, J=8.7 Hz, 1H), 5.29 (br. s., 1H), 7.42-7.48 (m, 1H), 7.54 (td, J=7.7, 1.3 Hz, 1H), 7.96 (s, 1H), 8.02 (dd, J=15.2, 7.6 Hz, 2H), 8.14 (s, 1H), 8.21 (d, J=2.3 Hz, 1H), 8.33 (d, J=2.3 Hz, 1H).
