2-amino-1-(4-chlorophenyl)ethanol;hydrochloride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 4-(6-chloro-4-(ethoxycarbonyl)chroman-7-yloxy)benzoic acid (0.050 g, 0.13 mmol), 2-amino-1-(4-chlorophenyl)ethanol hydrochloride (0.033 g, 0.16 mmol), N-ethyl-N-isopropylpropan-2-amine (0.030 ml, 0.17 mmol), and 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (0.018 g, 0.13 mmol) in DMF (1 ml) was added N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (0.031 g, 0.16 mmol), and the reaction was stirred at ambient temperature for 16 hours. It was diluted with EtOAc and washed with 10% citric acid, saturated sodium bicarbonate, and saturated sodium chloride. It was dried over anhydrous sodium sulfate, filtered, and concentrated. The crude material was on a Biotage SP1 system using a 25-100% EtOAc/hexanes linear gradient to yield 56 mg of the title compound (80% yield). washed with 10% citric acid, saturated sodium bicarbonate, and saturated sodium chloride It was dried over anhydrous sodium sulfate filtered concentrated
