실험 절차

Prepared using General Procedure 12. To a stirred solution of (S)-5-(5-(1-amino-2,3-dihydro-1H-inden-4-yl)-1,3,4-thiadiazol-2-yl)-2-isopropoxybenzonitrile hydrochloride 4 (20 mg, 0.04 mmol) and TEA (14.7 mg, 0.14 mmol) in DCM (2 mL) was added methane sulfonylchloride (8.3 mg, 0.07 mmol) and the mixture was stirred at room temperature for 16 h. The solvent was evaporated and the residue purified by preparative HPLC to afford 12 mg (55%) of (S)-N-(4-(5-(3-cyano-4-isopropoxyphenyl)-1,3,4-thiadiazol-2-yl)-2,3-dihydro-1H-inden-1-yl)methanesulfonamide 33 as white solid. LCMS-ESI (m/z) calculated for C22H22N4O3S2: 454.1; found 455.1 [M+H]+, tR=3.48 min.
