After stirring at 0° C. for 30 min. the reaction mixture was partitioned between CH2Cl2 and water. The organic layer was separated and the aqueous layer was extracted with CH2Cl2 (2×). The combined organic phase was dried over magnesium sulfate and the solvent removed under reduced pressure. The resulting residue was purified by filtration through an SPE Cartridge (Aminopropyl NH2, 500 mg/6 mL) to give the desired product (26 mg, 32%).
