Procedure

To a stirred solution 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 (82 mg; 0.19 mmol) in DMF (5 ml) was added HATU (103 mg; 0.27 mmol), DIPEA (50 μl; 0.27 mmol) and (R)-(+)-3-(dimethylamino)pyrrolidine (50 μl; 0.38 mmol). The reaction mixture was stirred at room temperature for 4 h upon which time it was diluted with EtOAc (20 ml) and washed successively with satd. NaHCO3 (20 ml) and brine (2 20 ml). The organic layer was dried (Na2SO4), concentrated and purified by prep. LCMS to give 418 as an off-white solid (53 mg; 53%). δH (400 MHz, CDCl3) 1.80-1.95 (m, 1H), 2.03-2.15 (br m, 1H), 2.24 (br s, 3H), 2.35 (br s, 3H), 2.62-2.85 (br m, 1H), 3.16 (br s, 2H), 3.30-4.00 (m, 4H), 4.33 (br s, 2H), 6.92-7.20 (m, 4H), 7.40 (br s, 1H), 7.51-7.61 (m, 1H), 7.77 (s, 1H), 8.11 (s, 1H). [M+H]+: 522
