4-Methylmorpholine → [4-(Morpholin-4-yl)phenyl]methanol

Participants

Reaction Steps

A solution of 4-(4-morpholinyl)benzoic acid (1.00 g, 4.83 mmol) and 4-methylmorpholine (0.53 mL, 4.8 mmol) in tetrahydrofuran (25 mL) at −10° C. was treated with ethyl chloroformate (0.46 mL, 4.8 mmol). After 0.25 h, the mixture was treated with sodium borohydride (550 mg, 14.5 mmol) followed by MeOH (50 mL) slowly. The mixture was then treated with 5% HOAC in water and the mixture was concentrated . The residue was purified by chromatography (SiO2, EtOAc:hexanes) yielding 164 mg (18%) of the title compound.
