Reaction Steps

2.14 mL (22.0 mmol) 2-chloropropionic acid chloride in 5 mL DCM is added dropwise to a solution of 3.46 g (20.0 mmol) 2-amino-5-bromopyridine and 6.12 mL (44.0 mmol) triethylamine in 80 mL DCM at 0° C. The ice bath is removed and the reaction solution is stirred for a further 1.5 h at RT. Another 0.40 mL (4.12 mmol) 2-chloropropionic acid chloride is added and the solution is stirred for a further hour at RT. The reaction mixture is combined with 80 mL water, washed once with 80 mL saturated NaCl solution and dried over MgSO4. The solvent is eliminated i.vac. and the residue is triturated with a little EtOAc, suction filtered and dried.
