Procedure
A mixture of 3.5 ml (21.8 mmol) of 2-isopropylpyrazolo[1,5-a]pyridine, 2 ml (10.5 mmol) of 2-chloro-phenylacetyl chloride and 300 mg of AlCl3 were stirred at RT for 4 days. The resulting 1.5 g of crude chloride was dissolved in 150 ml of MeOH, and reacted with NH3 (gas) in presence of 20 mg of NaI at 400° C. for 3 days to get 1.2 g of crude product, followed by purification on an Al2O3 column to obtain 220 mg of 2-amino-1-(2-isopropylpyrazolo[1,5-a]pyridin-3-yl)-2-phenylethanone. Compound 1039.
