Procedimiento

A solution, under argon, of 0.183 g of product from Example 140 in 1.0 ml of dry methylene chloride is treated with 0.689 g of tetra-n-butyl-ammonium azide. The reaction mixture is stirred vigorously overnight at room temperature. The reaction is concentrated in vacuo and the residue purified by chromatography (silica gel: 0-10% diethyl ether/hexane) to give 0.061 g of the desired product.
