Reaction Conditions:
with potassium carbonate in dichloromethane;water; for 15 h;
Steps:
5a.a
a) 4,5,6,7-Tetrahydro-2H-pyrazolo[4,3-b]pyridine.HCl (319 mg, 2 mmol) was combined with Boc2O (480 mg, 2.2 mmol) and K2CO3 (1.3 mL, 3 M aqueous, 2 equiv) in CH2Cl2 (10 mL). After 15 hours, the starting amine was consumed (LCMS). The reaction slurry was washed with brine and the organic layer was dried on MgSO4, filtered, and concentrated to give a viscous yellow oil (446 mg, 96%) that was used without further purification. MS: (ES) m/z calculated for C11H18N3O2 [M+H]+ 224.1, found 224.2.
