Reaction Steps

Following the procedure for Example 339, 2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a,9-triaza-benzo[e]azulen-8-ol from Example 93 and (2S,4R)-2-carbamoyl-4-cyano-pyrrolidine-1-carboxylic acid tert-butyl ester were reacted. The crude product was subjected to flash chromatography (SiO2, gradient 0 to 10% methanol in DCM) to give 430 as an off-white solid (41 mg, 72%). LCMS: RT=2.85 min, [M+H]+=435. 1H NMR 400 MHz (DMSO-d6) δ: 9.08 (1H, s), 7.88 (1H, d, J=0.63 Hz), 7.85 (1H, s), 7.56 (1H, br, s), 7.11 (1H, br, s), 6.04 (1H, s), 5.94-5.93 (1H, m), 4.51 (4H, d, J=15.42 Hz), 4.44 (1H, d, J=5.97 Hz), 3.92 (1H, dd, J=10.05, 7.55 Hz), 3.72 (1H, t, J=8.49 Hz), 3.61-3.53 (1H, m), 2.55-2.54 (1H, m), 2.35 (1H, ddd, J=12.61, 6.87, 3.63 Hz), 1.47 (6H, dd, J=6.59, 3.21 Hz)
