Reaction Steps
A mixture of (3-(bromomethyl)-pyrazolo[3,4-b]pyridine-1-yl)acetic acid ethyl ester (0.5 Mmol, 1 eq.) and sodium azide (1 Mmol, 2 eq.) in 1 mL of DMF was heated at 80° C. for 1 h. The resultant mixture was cooled to rt, diluted with 150 mL of EtOAc, washed with water (40 mL××3), brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The solvent was removed in vacuo to provide 135.2 Mg desired product: HPLC retention time=1.84 minutes (Agilent Zorbax SB-C18, 2.1×50 Mm, 5μ, 35° C.) using 1 mL/min flow rate, a 2.5 minute gradient of 20% to 100% B with a 1.1 minute wash at 100% B (A=0.1% formic acid/5% acetonitrile/94.9% water, B=0.1% formic acid/5% water/94.9% acetonitrile); MS (ES) M+H expect=261.1, found=261.4.
