YieldReaction ConditionsOperation in experiment
With 4-methyl-morpholine; HATU; In N,N-dimethyl-formamide; at 20℃; for 0.5h; Step 1: A solution of <strong>[6398-87-4]3-(1,3-dioxolan-2-yl)aniline</strong> (3.26 g, 19.7 mmol), 4-bromopicolinic acid (4.38 g, 21.7 mmol), (2-(7-Aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU) (8.99 g, 23.6 mmol), and N-methylmorpholine (2.6 mL, 23.6 mmol) in N,N-dimethylformamide was stirred at room temperature for 30 minutes. The solvent was removed under reduced pressure, and the residue was purified by flash chromatography (1:1 Hexanes/ethyl acetate) to afford a mixture of N-(3-(1,3-dioxolan-2-yl)phenyl)-4-bromopicolinamide acetal and the corresponding aldehyde (5.56 g, ~81% yield, contains ~15% aldehyde). M+1=349.1

YieldReaction ConditionsOperation in experiment
With benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; triethylamine; In N,N-dimethyl-formamide; at 20℃; for 18h; A mixture of 4-bromopicolinic acid ( 15 g, 75 mmol), methanamine hydrochloride (1 5 g, 75 mmol), HOBt (10 g, 75 mmol), EDCI (21 g, 75 mmol) and Et3N (41.5 mL, 300 mmol) in DMF(200 mL) was stirred at r.t. for 18 h. Water was added to the reaction mixture and the resulting mixture was filtered to afford 16 g of 78 as solid which was used directly in the next step. LCMS: m/z 215 (M+l )+
