Example 6: Preparation of c/s-adamantane-2-spiro-3′ -8 ‘-πT(2′-amino-2′ -methyl propyl) amino! carbonyl] methyli-l ‘, 2\ 4′-U-JoXaSpJrQ [4.51 decane maleate To a solution of c/s-adamantane-2-spiro-3′-8′-[[[(2′-amino-2′-methyl propyl) amino] carbonyl] methyl]-! ‘, 2′, 4′-trioxaspiro [4.5] decane (example 5) (60 g, 0.153 moles) in ethanol (150 mL) was added a solution of maleic acid (17.3 g, 0.15 moles, 0.98 equiv. in ethanol 90 mL) and the reaction mixture was stirred for about 1 h. To this clear solution, n- heptane (720 mL) was added at room temperature in 1 h and the reaction mixture was stirred for 3 h. It was then cooled to 0 to 10⁰C and filtered. The cake was washed with n-heptane (60 mL) and dried under vacuum at 40-45⁰C.
