Reaction Steps

According the the procedure of J. Am. Chem. Soc., 74, 1952 (1959), combine butyrolactone (8.6 g, 100 mmol) and (R)-α-methylbenzylamine (15.0 g, 123 mmol) and heat to 180° C. After 48 hours, heat to 210° C. After 6 hours, cool the reaction mixture and evaporate in vacuo using a short path distillation apparatus to obtain a residue: bp 110° C. at 0.5 mm Hg. Chromatograph the residue on silica gel eluting with ethyl acetate to give the title compound: Rf=0.45 (silica gel, ethyl acetate).
