Procedure

Following the procedure for Examples 339 and 408, 2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a,9-triaza-benzo[e]azulen-8-ol and (2S,4R)-4-methoxy-pyrrolidine-2-carboxylic acid amide were reacted. The reaction mixture was diluted with water passed down an SCX-2 cartiridge, washed with DCM, ethyl acetate and methanol and products eluted with 2M ammonia in methanol. Appropriate fractions were concentrated in vacuo and the resultant residue was triturated in diethyl ether and methanol, filtered and dried to give 407 as beige solid (45 mg, 32%). LCMS: RT=2.60 min, [M+H]+=439. 1H NMR 400 MHz (CDCl3) δ: 9.27 (1 H, s), 7.83 (1 H, s), 7.57 (1 H, s), 6.79 (1 H, br, s), 6.00 (1 H, s), 5.98 (1 H, m), 5.29 (1 H, br, s), 4.65 (1 H, dd, J=8.28, 4.87 Hz), 4.49-4.47 (2 H, m), 4.39-4.34 (2 H, m), 4.23 (1 H, t, J=5.53 Hz), 3.74 (1 H, dd, J=10.34, 5.70 Hz), 3.51-3.46 (1 H, m), 3.36 (3 H, s), 2.52-2.51 (1 H, m), 2.24-2.23 (1 H, m), 1.55-1.54 (6 H, m)
