Triethylamine → HCID 59161057, compound

Participants

Reaction Steps

The crude product from Example 2A is dissolved in 20 ml of dichloromethane, and 0.83 ml (5.93 mmol) of triethylamine and 1.54 ml (5.93 mmol) of tert-butyldiphenylchlorosilane are added. After addition of 24.2 mg (0.20 mmol) of 4-N,N-dimethylaminopyridine the mixture is stirred at RT for 20 h. In each case 10 ml of ethyl acetate and of saturated aqueous sodium bicarbonate solution are then added. The phases are separated, and the combined organic phases are then dried over magnesium sulfate. The solvent is removed on a rotary evaporator and the residue is purified chromatographically on silica gel 60 (mobile phase: gradient cyclohexane/ethyl acetate 100:1→20:1).
