Procedure
Combine the acetonide (2) (638 mg, 1.87 mmol) with D-(+)-amphetamine (4.5 g) and heat to 130° C. for 5 hours under nitrogen with stirring. After cooling, purify by flash chromatography (3% to 5% to 10% methanol/chloroform) followed by radial chromatography four times (2% to 4% to 6% to 8% to 10% methanol/chloroform, 4 mm plate) to provide the secondary amine (3) (0.56 g).
