실험 절차

Prepared using General Procedure 6. To the solution of (R)-5-(3-(1-amino-2,3-dihydro-1H-inden-4-yl)-1,2,4-oxadiazol-5-yl)-2-isopropoxybenzonitrile 49 (90.0 mg, 0.25 mmol) and K2CO3 (103.5 mg, 0.75 mmol) was added methyl 3-bromopropanoate (41.8 mg, 0.25 mmol). The reaction was heated to 80° C. for 30 min and repeated four time at 80° C. for 30 min with additional methyl 3-bromopropanoate (41.8 mg, 0.25 mmol) added each time. The solvent was evaporated, and the residues partitioned between EA and water. The organic layer was collected, dried over MgSO4, and purified by chromatography (MeOH/DCM with 0.025% TEA) to give 71 mg (63%) of (R)-methyl 3-((4-(5-(3-cyano-4-isopropoxyphenyl)-1,2,4-oxadiazol-3-yl)-2,3-dihydro-1H-inden-1-yl)amino)propanoate as a solid. LCMS-ESI (m/z) calculated for C25H26N4O4: 446.5; found 447.2 [M+H]+, tR=2.61 min. 1H NMR (400 MHz, CDCl3) δ 8.40 (d, J=2.1, 1H), 8.31 (dd, J=8.9, 2.2, 1H), 8.04 (d, J=7.6, 1H), 7.49 (d, J=7.5, 1H), 7.35 (t, J=7.6, 1H), 7.09 (d, J=9.0, 1H), 4.77 (dt, J=12.2, 6.1, 1H), 4.31 (t, J=6.8, 1H), 3.73-3.58 (m, 3H), 3.43 (ddd, J=17.4, 8.7, 4.6, 1H), 3.24-3.08 (m, 1H), 3.04-2.85 (m, 2H), 2.56 (t, J=6.5, 2H), 2.47 (dtd, J=12.8, 8.4, 4.7, 1H), 1.99-1.82 (m, 1H), 1.54-1.32 (m, 6H).
