Reaction Steps

Prepared using General Procedure 11. To a solution of 2-hydroxy-5-(3-(1-(2-hydroxyethylamino)-2,3-dihydro-1H-inden-4-yl)-1,2,4-oxadiazol-5-yl)benzonitrile 102 (15.0 mg, 0.041 mmol) in DMA (2 mL) was added K2CO3 (16.9 mg, 0.12 mmol) and 1-bromo-2-methylpropane (11.3 mg, 0.08 mmol). The mixture was stirred 6 h at 75° C. The solvent was evaporated and the mixture was partitioned between EA and brine. The organic layer was dried over MgSO4, filtered, and the solvent evaporated. The final compound was purified by preparative HPLC to give 6.31 mg (37%) of 5-(3-(1-((2-hydroxyethyl)amino)-2,3-dihydro-1H-inden-4-yl)-1,2,4-oxadiazol-5-yl)-2-isobutoxybenzonitrile 103 as a white solid. LCMS-ESI (m/z) calculated for C24H16N4O3: 418.5; found 419.2 [M+H]+, tR=2.61 min.
