Reaction Steps

4-(3-Chloro-4-fluorophenyl)-3-(4-[(2-morpholin-4-ylethyl)amino]methyl-1,2,5-oxadiazol-3-yl)-1,2,4-oxadiazol-5(4H)-one (20 mg, 0.047 mmol) was dissolved in anhydrous ACN (200 μL) followed by addition of DIPEA (40 μL, 0.2 mmol) and methanesulfonyl chloride (4.0 μL, 0.052 mmol). The reaction was stirred at 40° C. for 2 hrs. The reactions was then diluted with MeOH and purified by HPLC. The purified fractions were concentrated to dryness, redissolved in EtOH (1 mL) and 2 M of sodium hydroxide in water (0.26 mL) was added. The reaction was stirred at rt for 2 hrs, quenched with acetic acid, diluted with MeOH and purified by preparative LCMS to afford the desired product (1.4 mg). MF═C17H22ClFN6O5S; LCMS calculated for C17H23ClFN6O5S(M+H)+: m/z=477.1.
