Procedure
The title compound was synthesized by the method given for Compound 7 using the following quantities: Compound V (R=1-naphthyl) (0.177 g, 0.5 mmol), 6-oxoheptanoic acid n-butylamide (0.100 g, 0.5 mmol), sodium cyanoborohydride (0.32 g, 0.5 mmol), methanol (2 ml). Purification of a portion of the product after extraction was achieved by semipreparative high pressure liquid chromatography using a C18 column, 1.3 ml/min flow rate with 64% methanol/0.01N hydrochloric acid as eluant. The appropriate fractions were combined, the solvent evaporated under reduced pressure and the residue lyophilized from methanol/water to give 13.8 mg of the hydrochloride salt of the desired compound. The purity of the product was verified by HPLC (1.2 ml/min, 64% methanol/0.01N hydrochloric acid, ret. time=20 min).
