Procedure

A mixture of 2-[2-(2,4-difluoro-phenyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1-thia-benzo[e]azulene-9-carboxylic acid (53 mg), HATU (61 mg) and diisopropylethylamine (0.028 mL) and ethanolamine was stirred in N,N-dimethylformamide (3 ml). The reaction mixture was stirred overnight, and then diluted with ethyl acetate, washed with water, dried (MgSO4) and the solvent removed in vacuo. Purification using flash chromatography yielded 398 (24 mg). NMR: (CDCl3): 2.30 (1H, t, br.), 3.05 (2H, t), 3.51-3.55 (2H, m), 3.7-3.75 (2H, m), 4.31 (2H, t), 6.40 (1H, br.), 6.80 (1H, s), 6.99 (1H, d), 7.05-7.12 (2H, m), 7.42-7.52 (2H, m), 7.90 (1H, s), 8.01 (1H, s). MS. ESI+510 (MH++MeCN)
