Reaction Conditions:
in dichloromethane;N,N-dimethyl-formamide at 0 - 20; for 2.33333 h;
Steps:
1 Intermediate 8: N-(pyridin-2-yl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide
20 g of 4- (4,4,5,5-tetramethyl-1,3,2-dioxolane-2-yl) benzoic acid is dissolved in 350 ml of dichloromethane,Cool down to 0-5 ° C.Add 1 ml of DMF, dropwise add 16 ml of oxalyl chloride, and stir at 0-5 ° C for 20 min; warm to room temperature and stir for 2 hr.The reaction solution was concentrated and stripped twice with dichloromethane.21.5 g of acid chloride were obtained and used directly in the next reaction.
