Yield:1254102-12-9 92%
Reaction Conditions:
with tetrabutyl ammonium fluoride in tetrahydrofuran at 20;
Steps:
5 Intermediate 5: (R)-5-(2-Azido-1-hydroxyethyl)-8-(benzyloxy)quinolin-2(1H)-one
A 1.0 M (THF) solution of TBAF (0.443 mL, 0.443 mmol) was added to a stirring solution of Intermediate 1 (200 mg, 0.443 mmol) in THF (4 mL) at rt. The resulting mixture was stirred over night then concentrated. Chromatography (1:3, Hexanes/EtOAc) afforded the title compound (137 mg, 92%) as an off-white solid. ES/MS calcd. for C18H17N4O3+ 337.1. Found m/z=337.2 (M+H)+.
