Procedure

Prepared using General Procedure 8A: To a stirred solution of (S)-5-(3-(1-amino-2,3-dihydro-1H-inden-4-yl)-1,2,4-oxadiazol-5-yl)-2-isopropoxybenzonitrile 50 (18 mg, 0.05 mmol) in DCM (1 mL) was added TEA (13.9 μL, 0.1 mmol) and methanesulfonyl chloride (19 mg, 0.1 mmol). After 1 h, additional TEA (13.9 μL, 0.1 mmol) and methanesulfonyl chloride (19 mg, 0.1 mmol) were added. After an additional 1 h of stirring the solvent was evaporated and purified by preparative HPLC to afford 9.8 mg (45%) of (S)—N-(4-(5-(3-cyano-4-isopropoxyphenyl)-1,2,4-oxadiazol-3-yl)-2,3-dihydro-1H-inden-1-yl)methane sulfonamide 69. LCMS-ESI (m/z) calculated for C22H22N4O4S: 438.1; found 439.1 [M+H]+, tR=3.70 min. 1H NMR (400 MHz, CDCl3) δ 8.41 (d, J=2.2 Hz, 1H), 8.32 (dd, J=8.9, 2.2 Hz, 1H), 8.12 (d, J=7.7 Hz, 1H), 7.60 (d, J=7.6 Hz, 1H), 7.43 (t, J=7.6 Hz, 1H), 7.11 (d, J=9.0 Hz, 1H), 5.07 (dd, J=16.5, 7.8 Hz, 1H), 4.78 (hept, J=6.1 Hz, 1H), 4.48 (d, J=9.3 Hz, 1H), 3.51 (ddd, J=17.5, 8.8, 3.4 Hz, 1H), 3.29-3.12 (m, 1H), 3.09 (s, 3H), 2.74 (dtd, J=12.9, 8.0, 3.5 Hz, 1H), 2.07-1.92 (m, 1H), 1.46 (d, J=6.1 Hz, 6H).
