Reaction Steps
1-sec-butyl-N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-2-methyl-1H-indole-3-carboxamide (35 mg, 0.1 mmol) was separated by chiral prep-HPLC (Daicel IA (200 mm×20 mm×5 um), hexane: ethanol (0.2% DEA)=70:30, flow rate: 19 mL/min), then (R or S) 1-sec-butyl-N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-2-methyl-1H-indole-3-carboxamide (11 mg, 30%) and (S or R)-1-sec-butyl-N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-2-methyl-1H-indole-3-carboxamide (6 mg, 16%) was obtained. The retention times were 8.030 minutes (“Peak 1”; Compound 147) and 14.126 minutes (“Peak 2”; Compound 148) respectively in chiral HPLC chromatography. LRMS (M+H+) m/z: calcd 365.2. found 365. HPLC purity (214 nm): 99%. 1H. NMR (300 MHz, CD3OD): δ 7.73-7.70 (m, 1H), 7.56-7.53 (m, 1H), 7.12-7.09 (m, 2H), 6.11 (s, 1H), 4.54 (s, 3H), 2.64 (s, 3H), 2.43 (s, 3H), 2.25 (s, 3H), 1.97-1.90 (m, 2H), 1.61 (d, J=6.9 Hz, 3H), 0.73 (t, J=7.5 Hz, 3H).
