Prepared using General Procedure 7: 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 (15 mg, 0.03 mmol) in anhydrous DCM (1 mL) was added triethylamine (11 mg, 0.1 mmol) followed by acetyl chloride (4.2 mg, 0.05 mmol) and the reaction mixture was stirred at room temperature overnight. The solvent was evaporated and the crude mixture purified by preparative HPLC to afford (S)-N-(4-(5-(3-cyano-4-isopropoxyphenyl)-1,3,4-thiadiazol-2-yl)-2,3-dihydro-1H-inden-1-yl)acetamide 14. LCMS-ESI (m/z) calculated for: C23H22N4O2S: 418.2; found 419.3 [M+H]+, tR=3.34 min. 1H NMR (400 MHz, CDCl3) δ 8.20 (dd, J=8.9, 2.3 Hz, 1H), 8.13 (d, J=2.2 Hz, 1H), 7.81 (d, J=7.6 Hz, 1H), 7.45 (d, J=7.5 Hz, 1H), 7.36 (t, J=7.6 Hz, 1H), 7.08 (d, J=9.0 Hz, 1H), 5.83 (d, J=8.4 Hz, 1H), 5.57 (q, J=7.9 Hz, 1H), 4.76 (dt, J=12.2, 6.1 Hz, 1H), 3.46 (ddd, J=17.1, 8.8, 3.8 Hz, 1H), 3.28-3.15 (m, 1H), 2.75-2.62 (m, 1H), 2.07 (s, 3H), 1.98-1.80 (m, 1H), 1.46 (d, J=6.1 Hz, 6H). 13C NMR (101 MHz, CDCl3) δ 170.36, 167.43, 166.14, 162.16, 145.92, 142.83, 133.89, 133.77, 129.44, 128.23, 127.18, 126.95, 123.21, 116.05, 114.36, 104.23, 73.03, 55.00, 34.03, 31.95, 23.92, 22.24.
