Reaction Steps

Dissolve 3-(2-amino-1-hydroxy-3-phenylpropyl)-7-methoxymethyl-2-azabicyclo[2.2.1]heptane-2-carboxylic acid tert-butyl ester (0.243 mg, 0.622 mmol) in tetrahydrofuran (3 mL) and cool the mixture in an ice bath. Add triethylamine (0.091 mL, 0.653 mmol) and acetic anhydride (0.059 mL, 0.622 mmol) in tetrahydrofuran (2 mL). Stir the mixture at room temperature for 1 h. Add dichloromethane (30 mL) and water (10 mL). Separate layers and wash the organic layer with 0.5 N HCl, saturated aqueous sodium bicarbonate, dry (magnesium sulfate), concentrate and purify (silica gel chromatography, eluting with 3-5% isopropyl alcohol/47-45% dichlomethane in 50% hexanes) to give the title compound Isomer-1 (0.044 g, 16%) and Isomer-2 (0.077 mg, 29%).
