Procedure

To a solution of tert-butyl 5-(2-ethoxy-2-oxoethoxy)-3,4-dihydroisoquinoline-2(1H)-carboxylate (400 mg, 1.19 mmol) in ethyl acetate (10 mL), cooled in an ice-water bath, was added (10 mL, 1N) drop wise. The mixture was stirred at 25° C. for 16 h and then concentrated under vacuum to give the crude product (275 mg, 98%) which was used to the next step without further purification.
