Reaction Steps
3-Amino-5-bromo pyridine (XX) (1.0 g, 5.78 mmol) was dissolved in pyridine and cooled to 0° C. before adding dimethyl carbamyl chloride (XXI) (0.683 g, 6.35 mmol). The reaction mixture was stirred at room temperature for 2 h and then heated overnight at 60° C. under argon. The solution was cooled to room temperature, poured into ice water and extracted with EtOAc. The organic extract was dried over MgSO4, filtered and concentrated to a residue to afford 3-(5-bromopyridin-3-yl)-1,1-dimethylurea (XXII) as a brown solid, (1.24 g, 5.09 mmol, 88% yield). 1H NMR (DMSO-d6) δ ppm 8.67-8.64 (m, 2H), 8.23 (d, J=7.8 Hz, 1H), 2.93 (s, 6H); ESIMS found for C8H10BrN3O m/z 245.05 (M+H).
