Reaction Steps

14.0 mg (0.10 mmol) of 1-(1-methyl-1H-pyrazol-4-yl)ethane-1,2-diamine were initially charged in a 96-well deep well multititre plate. A solution of 35.1 mg (0.10 mmol) of 7-[(2,6-difluorobenzyl)oxy]-2,5-dimethylpyrazolo[1,5-a]pyridine-3-carbonyl chloride in 0.6 ml of dichloroethane and 0.032 ml (0.40 mmol) of pyridine were added successively and the mixture was stirred at RT overnight. Then the solvent was evaporated off completely, the residue was dissolved in 0.8 ml of DMF and filtered, and the target compound was isolated from the filtrate by preparative LC-MS (Method 9). The product-containing fractions were concentrated under reduced pressure using a centrifugal dryer. The residue of each product fraction was dissolved in 0.6 ml of DMSO. These were combined and finally freed of the solvent in a centrifugal dryer. 18 mg (37% of theory; 94% purity) of the title compound were obtained.
