Cesium carbonate → HCID 59300455, compound

Participants

Reaction Steps

6-Ethyl-2-methyl-3-pyridinol (40.6 mg, 0.30 mmol) and [(1S)-5-(3-bromopropoxy)-2,3-dihydro-1H-inden-1-yl]acetate (101.0 mg, 0.30 mmol) (Example 45) were dissolved in DMF (4 mL) and cesium carbonate (193 mg, 0.59 mmol) and 4 drops of water were added. The mixture was stirred at rt for 16 h. The DMF was removed in vacuo and the residue was suspended in EtOAc and filtered. This filtrate was concentrated to give the pure title compound as a yellow oil (73 mg, 62%) which was used in the next step without further purification. 1H NMR (400 MHz, CDCl3): δ 7.08-6.99 (m, 2H), 6.90 (d, 1H), 6.78 (s, 1H), 6.62 (dd, 1H), 4.20-4.08 (m, 4H), 3.72 (s, 3H), 3.58-3.48 (m, 1H), 2.96-2.70 (m, 6H), 2.51-2.34 (m, 4H), 2.30-2.23 (m, 2H), 1.80-1.68 (m, 1H), 1.21 (t, 3H).
