The resulting suspension was stirred at this temperature overnight. Water was added and then the aqueous layer extracted with DCM (×3). The combined organic extracts were dried (MgSO4), filtered and concentrated in vacuo to give the sub-title compound as a clear oil which was used directly in the next step without further purification.
