Procedure

To a solution of crude 2-amino-2-(7-(heptyloxy)quinolin-3-yl)propanoic acid (600 mg, 1.8 mmol) in dry THF (30 mL) was added LAH (138 mg, 3.6 mmol, 2 eq.) at 0° C. under N2. Then, the mixture was warmed to room temperature for 3 h. Then the reaction mixture was added water (1 mL), diluted (EA), filtered and dried (Na2SO4), evaporated to dryness to give the crude product, which was purified by prep-HPLC to give 2-amino-2-(7-(heptyloxy)quinolin-3-yl)propan-1-ol as white solid (200 mg, yield 35%). ESI-MS: 317 (M+H)+.
