Triphenylphosphine → HCID 58790022, compound

Participants

Reaction Steps

DEAD (0.96 mL, 6.07 mmol) was added to a solution of the compound 137 (1.78 g, 4.33 mmol), 2-morpholinoethanol (0.74 mL, 6.07 mmol) and triphenylphosphine (1.59 g, 6.07 mmol) in THF (43 mL). The reaction mixture was stirred at room temperature until completion of the reaction. The mixture was quenched with a saturated aqueous solution of ammonium chloride then extracted three times with ethyl acetate and 3 times with dichloromethane (with a bit of methanol inside). The combined organic layers were washed with water and brine, dried over anhydrous MgSO4, filtered and evaporated. The residue was triturated with diethyl ether, filtered and dried on a vacuum pump to afford title compound 138 as a yellow-brown solid (1.80 g, 79% yield). MS (m/z): 526.2 (M+H).
