Yield:-

Reaction Conditions:

with triethylamine in tetrahydrofuran;dichloromethane at 0 - 20;

Steps:

822.1 Step 1. Synthesis of 4-Chloro-pyridine-2-carboxylic acid dimethylamide
Step 1.Synthesis of 4-Chloro-pyridine-2-carboxylic acid dimethylamide: A solution of 4-chloro-pyridine-2-carbonyl chloride (1 eq) in dichloromethane was cooled to 0° C., whereupon triethylamine (2 eq) was added followed by dimethylamine (2 eq, 2M solution in THF).The solution was allowed to warm to room temperature and let stir overnight.It was then washed with 1M NaOH. The separated organic layer is dried over MgSO4, filtered, and concentrated to yield the desired product. HPLC, 1.82 min; MS: MH+=185.6
