실험 절차

To a mixture of 4-Benzyloxy-1-methoxymethyl-7-phenoxy-isoquinoline-3-carboxylic acid (79 mg, 0.19 mmol), NEt3 (56 μl, 0.4 mmol), and CH2Cl2 (5 ml) cooled with an ice bath was added ClCO2iBu (26.5 μl, 0.2 mmol) with stirring. After stirring for 15 min (R)-alanine tert-butyl ester hydrochloride (36 mg, 0.2 mmol) was added and the mixture was allowed to warm up to ambient temperature overnight with stirring. Subsequently; the mixture was concentrated in vacuo. To the residue was added water (10 ml) and a few drops of aqueous 6N HCl. The mixture was extracted with EtOAc (2×15 ml). The organic phase was dried over MgSO4 and concentrated in vacuo. Purification by flash column chromatography on silica gel using EtOAc as the eluent gave the title compound as a tan oil (88 mg); MS-(+)-ion: M+23=565.2.
