937046-98-5, Name is 7-Bromopyrrolo[2,1-f][1,2,4]triazin-4-amine, 937046-98-5, belongs to bromides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows.
In a Bohdan Miniblock N-(3-phenylbutyl)-3-(4,4,5,5-tetramethyl-1,3,2- dioxaborolan-2-yl)benzamide (15 mg, 0.040 mmol) and 7-bromopyrrolo[2,1- f][1,2,4]triazin-4-amine (16.9 mg, 0.079 mmol) were dissolved in DMF (400 mul). To the vial was added PdCl2(dppf)-CH2Cl2 adduct (3.23 mg, 3.95 mumol), followed by tripotassium phosphate (59.3 mul, 0.119 mmol). The reaction mixture was capped, degassed and purged with N2. After stirring 1 h at 100 C, the mixture was cooled to rt. The crude material was purified via preparative LC/MS with the following conditions: Column: XBridge C18, 19 x 200 mm, 5-mum particles; Mobile Phase A: 5:95 acetonitrile: water with 10-mM ammonium acetate; Mobile Phase B: 95:5 acetonitrile: water with 10- mM ammonium acetate; Gradient: 20-60% B over 20 min, then a 5-minute hold at 100% B; Flow: 20 mL/min. Fractions containing the desired product were combined and dried via centrifugal evaporation to yield the final product (6.8 mg, 17.6 mumol, 44 %).
