Reaktionsschritte

14.5 g of t-butylamine in 50 ml of acetone were added dropwise to a solution of 18.8 g of the compound from stage 2 (0.55 mols) in 150 ml of acetone at -5° to 0° C. The mixture was further stirred overnight, filtered off from the deposit, concentrated and crystallized from ether with a little acetonitrile. Yield: 19.2 g=92% of the theoretical yield; mp: 203°-206° C.
