Reaction Steps

To a solution of 2-[2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diazabenzo[e]azulen-8-yloxy]-2-methylbutane-1,4-diol (14 mg, 0.0318 mmol) and Et3N (13 uL, 0.095 mmol) in DCM (2 mL) at 0° C. was added methanesulfonyl chloride (6.0 uL, 0.080 mmol) and stirring at RT was continued for 1.5 h. The mixture was diluted with DCM, washed with a saturated solution of NaHCO3, followed by water, then dried (Na2SO4) and concentrated in vacuo affording Methanesulfonic acid 3-[2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diazabenzo[e]azulen-8-yloxy]-4-methanesulfonyloxy-3-methylbutyl ester as a colorless gum (23 mg, quantitative). LCMS: RT 2.99 min [M+H]+ 584.1
