Procedure
The product of stage (b) above (5.0 g) was added to trifluoroacetic acid (25 ml) and the resulting solution was stirred at room temperature for 3 hours. The solution was evaporated and the residue was triturated with diisopropyl ether and cooled in a solid carbon dioxide-acetone bath. The solid was filtered and washed with diisopropyl ether to give 3.5 g of the desired product, mp 136°-139° C.
