实验过程
0.5 g of the compound obtained in EXAMPLE 1' is added to a solution of 0.08 g of H2SO4 in 5 ml of MeOH, this solution is poured into 150 ml of ether cooled to 5° C., and the precipitate formed is drained. 0.54 g of the expected product is obtained. After recrystallization in water, m.p.=212° C. (dec.). After recrystallization in 2-isopropanol, m.p.=263° C.
