Reaction Steps

The title compound was synthesized as part of library using the following procedure in a parallel synthesis fashion using 48 well red and blue minireactors. Typical procedure: To a solution of 22B (14 mg, 0.05 mmol) in DCE (0.5 mL) at RT was added NMM (0.109 mL, 0.1 mmol), followed by addition of benzene sulfonylchloride (17.6 mg, 0.1 mmol) in DCE (0.5 uL). The reaction mixture was shaken at RT for 24 h, and treated with 100 mg of PS-Trisamine (4 mmol/g loading) for 2 h to remove excess sulfonyl chloride. Contents were filtered into a synthesis tube rack (STR) and the solvent was dried in a speed vac. The resulting residue was chromatographed using Prep HPLC (conditions: Xterra MS-C18 (30×50 mm); Eluted with 10% to 100% B, 6 min gradient. (A=100% water−0.1% TFA and B=acetonitrile with 0.1% TFA); Flow rate at 30 mL/min. UV detection at 220 nm) to give compound 50 (13.8 mg, 69%). HPLC: 99% at 1.74 min (retention time) (Conditions: Xterra MS-C18 (2.1×50 mm); Eluted with 0% to 100% B, 2.75 min gradient. (A=100% water−0.1% TFA and B=acetonitrile with 0.1% TFA); Flow rate at 1 mL/min. UV detection at 220 nm). MS (ES): m/z 413 [M+H]+.
