Participants

Reaction Steps

To a mixture of the compound of Example 89 (100 mg, 0.256 mmol) and caesium carbonate (202 mg, 0.62 mmol) in dry DMF (5 mL) was added 2-(chloroethyl)morpholine hydrochloride (58 mg, 0.31 mmol) and the reaction heated at 60° under nitrogen for 48 h. The reaction was partitioned between water and EtOAc, the EtOAc extracts dried (MgSO4) and concentrated in vacuo. The crude product was then purified by column chromatography on silica eluting with 0–5% MeOH in DCM to give the title compound as a white solid (68 mg). δH (CDCl3) 7.44–7.20 (8H, m), 7.04 (2H, d, J 9 Hz), 6.51 (1H, d, J 10 Hz), 4.15–4.03 (4H, m), 3.68 (4H, m), 2.79 (2H, t, J 6 Hz), 2.54 (4H, m), 1.05 (3H, t, J 7 Hz). LCMS (ES+) RT 2.53 minutes, 505 (M+H)+.
