Reaction Steps

A solution of 450 mg (1.5 mmol) of 2-amino-2-hydroxymethyl-4-(4-(octyl)phenyl)butanol, 0.32 mL (1.75 mmol) of triethylorthoacetate and 0.56 mL (3.2 mmol) of DIEA in 6 mL of DMF was stirred at 75° C. for 2 h. The mixture was cooled, partitioned between 40 mL of 3:1 v/v ether/EtOAc and water and the layers were separated. The organic layer was washed with water and dried. Flash chromatography on silica gel using 4:1 v/v CH2Cl2/EtOAc as the eluant afforded 440 mg (91%) of the title compound: Mass spectrum (NH3—CI) 332 (M+H).
