The mixture was filtered through a Millipore® filter and the filter cake was washed with ethanol. 3 ml (6.0 mmol) of 2 N hydrochloric acid in diethyl ether were added to the filtrate and the mixture was concentrated and dried under high vacuum. This gave 785 mg (111% of theory) of the target compound. The product was used without further purification for the next reaction.
