A solution of 8-azetidin-3-yl-2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulene hydrochloride from Example 65 (70 mg, 0.2 mmol) in NMP (2 mL) was treated with sodium phosphate tribasic (85 mg, 0.6 mmol) then N-methyl-2-chloro acetamide (24 mg, 0.22 mmol) in NMP (0.2 mL) and the mixture stirred at RT for 18 h. The mixture was loaded onto an Isolute® SCX-2 cartridge eluting with MeOH then 2M NH3 in MeOH. Appropriate fractions were combined and concentrated in vacuo, the resultant residue was subjected to flash chromatography (SiO2, gradient 0 to 10% MeOH in DCM) to give 212 (24 mg, 29%). 1H NMR δ (ppm) (CDCl3): 8.50 (1H, d, J=8.29 Hz), 7.89 (1H, s), 7.68 (1H, s), 7.22 (1H, s), 7.10 (1H, dd, J=8.33, 1.81 Hz), 6.99-6.96 (1H, m), 6.03-5.94 (1H, m), 4.53-4.49 (2H, m), 4.48-4.44 (2H, m), 3.96 (2H, t, J=7.77 Hz), 3.81 (1H, t, J=7.74 Hz), 3.54 (2H, t, J=7.43 Hz), 3.35 (2H, s), 2.86 (3H, d, J=4.93 Hz), 1.60 (6H, d, J=6.63 Hz). LCMS: RT=2.53 min, M+H+=422
