Reaction Steps
A 57% oil dispersion containing 0.6 g (0.025 mole) NaH was added in one portion to a solution of 4.7 g (0.023 mole) 1-hydroxy-4-(1,1-dimethylethoxycarbonyl)piperazine in 100 ml DMF under a dry N2 atmosphere. The mixture was stirred for 2 hours at room temperature and then 6.5 g (0.046 mole) iodomethane was added over 1 minute. After stirring for an additional 15 minutes, the mixture was poured into 100 ml H2O, stirred briefly, and extracted thoroughly with low boiling (35°-65° C.) petroleum ether. The extracts were dried (MgSO4), filtered and evaporated in vacuo to give 1.8 g of an oil. The oil was dissolved in ethyl ether, washed with dilute aqueous HCl, dried (MgSO4), filtered, and evaporated in vacuo to yield 1.3 g yellow oil. Short path distillation (Kugelrohr) returned 0.8 g colorless distillate, b.p.* 55°-65° C./0.15 mm. Calc. for C10H 20 N2O3 (216.28): C, 55.53; H, 9.32; N, 12.95; O, 22.19. Found: C, 55.61; H, 9.13; N, 12.96; O, 22.33.
