Versuchsvorschrift

At 5° C., 50 mL of a saturated solution of hydrogen chloride in diethyl ether were added dropwise to a mixture of 2.3 g of 7-methoxy-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester in 50 mL of diethyl ether and the reaction mixture stirred for 2 hours at room temperature. The precipitated product (hydrochloride) was separated by filtration, washed with diethyl ether and dried in vacuo. Yield: 1.5 g (7.5 mmol); m.p. 215-218° C.; EI-MS: 163 (M+).
