实验过程

A solution of 4-{[5-(aminomethyl)-1,6-diethyl-1H-pyrazolo[3,4-b]pyridin-4-yl]amino}-1-piperidinecarboxamide (0.21 g, 0.6 mmol, e.g. which can be as prepared in Intermediate 17) and triethylamine (0.21 ml, 1.52 mmol, 2.5 equivalents) in dichloromethane (20 ml) was stirred and cooled in an ice/water bath under an atmosphere of nitrogen. 4-{4-[(4-Bromobutyl)oxy]butyl}benzoyl chloride (0.32 g, 0.91 mmol, 1.5 equivalents, e.g. which can be as prepared in Intermediate 26) was added portion-wise over 2 minutes, and the mixture was stirred at 0° C. for 10 minutes and then at room temperature overnight. Iced water was added to the reaction mixture and the organic phase was separated and collected through a hydrophobic frit. The aqueous phase was extracted with dichloromethane (50 ml), and the combined organic extracts were evaporated to dryness to give a whitish foam. The residue was purified by passing through a 20 g silica column, eluting with a gradient of cyclohexane/ethyl acetate followed by a gradient of ethyl acetate/methanol. The fractions containing the product (obtained from 9:1 ethyl acetate/methanol) were pooled and evaporated to dryness to give the title compound as a pale yellow foam (0.27 g). LCMS showed MH+=656/658 (Bromine isotope pattern); TRET=2.88 min.
