Versuchsvorschrift

To a solution of 4-(1-ethyl-3-(pyridin-2-yl)-4,6,7,8-tetrahydro-1H-pyrazolo[3,4-e][1,4]thiazepin-4-yl)-3-methylbenzoic acid (0.60 g, 1.521 mmol, Preparation # V.1) and DIEA (0.80 mL, 4.56 mmol), in DMF was added HATU (0.64 g, 1.67 mmol). The reaction mixture was stirred for about 30 min and 1-methyl-1H-pyrazol-5-amine (0.22 g, 2.28 mmol, Aldrich) was added. The reaction mixture stirred for about 5 h and was concentrated under reduced pressure. The residue was dissolved in DCM (15 mL) and washed with saturated NaHCO3 (5 mL). The organic layer was separated and dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by RP-HPLC (Table 2, Method e), to afford 4-(1-ethyl-3-(pyridin-2-yl)-4,6,7,8-tetrahydro-1H-pyrazolo[3,4-e][1,4]thiazepin-4-yl)-3-methyl-N-(1-methyl-1H-pyrazol-5-yl)benzamide (0.30 g, 0.64 mmol, 42%) as a white solid. LC-MS (Table 1, Method g) Rt=2.01 min, m/z 474 (M+H)+; 1H NMR (DMSO-d6) δ 10.11 (s, 1H), 8.52-8.48 (m, 1H), 7.87-7.81 (m, 1H), 7.76-7.70 (m, 2H), 7.62 (dd, J=8.1, 1.8 Hz, 1H), 7.36 (d, J=1.9 Hz, 1H), 7.33 (d, J=8.1 Hz, 1H), 7.24-7.18 (m, 1H), 6.89 (s, 1H), 6.19 (d, J=1.9 Hz, 1H), 5.83 (d, J=4.6 Hz, 1H), 4.31-4.00 (m, 2H), 3.76-3.68 (m, 1H), 3.65 (s, 3H), 3.06-2.95 (m, 1H), 2.77-2.62 (m, 2H), 2.60 (s, 3H), 1.34 (t, J=7.1 Hz, 3H).
