Reference of 59020-10-9 ,Some common heterocyclic compound, 59020-10-9, molecular formula is C17H31NSn, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
34a. 5-(3-Pyridinyl)-6-chloro-3-(1-BOC-2-(S)-pyrrolidinylmethoxy)pyridine To a solution of 5-bromo-6-chloro-3-(1-BOC-2-(S)-pyrrolidinylmethoxy)pyridine (from Example 23a, 500 mg, 1.28 mmol) in toluene (10.0 mL) was added 3-pyridinyltributyltin (564 mg, 1.5 mmol) and tetrakis(triphenylphosphine)palladium(0) (45 mg, 0.039 mmol). After being refluxed overnight, the resulting mixture was cooled to room temperature. Solvent was removed and the residue was chromatographed on a silica gel column, eluding with hexane/EtOAc 2:1 and 1:1 to afford an oil (428 mg, 86%). MS (CI/NH3) m/z 390 (M+H)+. 1H NMR (CDCl3, 300 MHz) delta 1.24-1.67 (m, 2H), 1.44 (s, 9H), 1.86-2.10 (m, 2H), 3.32-3.45 (m, 2H), 3.95-4.27 (m, 3H), 7.28-7.44 (m, 2H), 7.81-7.86 (m, 1H), 8.14-8.17 (m, 1H), 8.65-8.73 (m, 2H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,59020-10-9, its application will become more common.
