Procedure

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 glycinamide hydrochloride salt in NMP were heated at 85° C. for 20 h. The reaction mixture was cooled and loaded onto an Isolute SCX-2 cartridge, washed with methanol and eluted with 2M ammonia in methanol and appropriate fractions concentrated in vacuo. The resultant residue was subjected to flash chromatography (SiO2, gradient 0 to 10% 2M ammonia in methanol in DCM). The solid was recrystallised from methanol to give 404 as a white solid (19 mg, 8%). LCMS: RT=2.14 min, [M+H]+=369. 1H NMR 400 MHz (DMSO-d6) δ: 9.01 (1H, s), 7.90 (1H, d, J=0.63 Hz), 7.82 (1H, s), 7.32 (1H, br, s), 7.01 (1H, br, s), 6.11 (1H, s), 5.97-5.88 (1H, m), 4.49-4.48 (4H, m), 3.84 (2H, d, J=4.26 Hz), 1.48 (6H, d, J=6.60 Hz)
