Procedure
A mixture of 4 g of the compound obtained in step A of Example 5a, 2.65 g of K2CO3 in 9.2 ml of water and 16 ml of n-butanol is heated at 90° C. for 12 hours. After cooling to RT, 19.2 ml of 2N HCl are added. The white precipitate formed is washed with 3 times 200 ml of water and then 3 times 200 ml of ethyl ether. 3.1 g of the expected product are obtained: m.p.=241° C.
