Reaction Steps

A solution of 5 N hydrochloric acid in ether (5 ml) was added to a solution of 4-(6,7-Dimethoxy-3,4-dihydro-1H-isoquinoline-2-carbonyl)-piperidine-1-carboxylic acid tert-butyl ester (3 g, 7.43 mmol) in ethyl acetate and the mixture was stirred for 2 hours at room temperature. The precipitate formed was collected by filtration and the white solid obtained was indetified as (6,7-dimethoxy-3,4-dihydroisoquinolin-2(1H)-yl)(piperidin-4-yl)-methanone (2.1 g, 95% yield).
