885279-92-5, 1-Boc-1,8-diaza-spiro[4.5]decane is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a stirred solution of C2 and TEA (1.2 eq) in DMF (0.3 M) was added TBTU (1.3 eq). The mixture was and stirred for Ih and tert-butyl l,8-diazaspiro[4.5]decane-l-carboxylate together with TEA (4 eq) was added. The mixture was stirred for 2h and the product was purified by preparative RP-HPLC, using H2O/ACN (0.1% TFA) as eluents. The pooled fraction were concentrated under reduced pressure and the remaining oil was (C3) stirred for 30 min in a mixture of TFA/DCM (1:1). The solvents were removed under reduced pressure and the residue was lyophilized from H2O/ ACN. The title compound was obtained as a slightly orange foam.1U NMR (400 MHz, DMSO-d6) delta: 8.65 (2H, br. s), 8.17-8.10 (IH, m), 7.86 (s, IH), 7.84- 7.75 (m, 2H), 7.52-7.41 (m, 2H), 7.36-7.25 (m, 2H), 5.74 (s, 2H), 4.10-3.99 (m, IH), 3.31-3.07 (m, 5H), 2.00-1.72 (m, 6H), 1.69-1.60 (m, 2H). MS (ES) C24H25FN4O2 requires: 420, found: 421 (M+H)+., 885279-92-5
As the paragraph descriping shows that 885279-92-5 is playing an increasingly important role.
