Prepared using General Procedure 22: To a stirred solution of (R)-5-(3-(1-amino-2,3-dihydro-1H-inden-4-yl)-1,2,4-oxadiazol-5-yl)-2-isopropoxybenzonitrile 49 (50 mg, 0.14 mmol) in dioxane (1.5 mL) was added sulfamide (66 mg, 0.69 mmol) and the mixture was heated to 110° C. After 14 h of stirring, the solvent was evaporated and the residue was purified by column chromatography. Additional purification by recrystallization from MeOH provided 15.9 mg (26%) of (R)—N-(4-(5-(3-cyano-4-isopropoxyphenyl)-1,2,4-oxadiazol-3-yl)-2,3-dihydro-1H-inden-1-yl)sulfamide 248. LCMS-ESI (m/z) calculated for C21H21N5O4S: 439.5; found 440.1 [M+H]+, tR=3.42 min. 1H NMR (400 MHz, CDCl3) δ 8.41 (d, J=2.1 Hz, 1H), 8.33 (dd, J=8.9, 2.2 Hz, 1H), 8.13 (d, J=7.6 Hz, 1H), 7.65 (d, J=7.6 Hz, 1H), 7.43 (t, J=7.7 Hz, 1H), 7.12 (d, J=9.0 Hz, 1H), 5.08 (dd, J=16.1, 7.9 Hz, 1H), 4.80 (dt, J=12.1, 6.1 Hz, 1H), 4.65 (s, 1H), 4.59 (d, J=8.4 Hz, 1H), 3.50 (ddd, J=17.5, 8.8, 3.7 Hz, 1H), 3.30-3.09 (m, 1H), 2.87-2.67 (m, 1H), 2.07 (dt, J=21.3, 8.2 Hz, 1H), 1.47 (t, J=6.3 Hz, 6H).
