Reaction Steps
To a solution of ethyl 2-((1,2,3,4-tetrahydroisoquinolin-5-yl)oxy)acetate (300 mg, 1.28 mmol) and Et3N (387 mg, 3.83 mmol) in DCM (25 mL) cooled in an ice-water bath was added MsCl (176.6 mg, 1.54 mmol) drop wise. The mixture was stirred at 25° C. for 16 h and then quenched with aq.NH4Cl. The mixture was extracted with ethyl acetate and the combined organic layers were concentrated under vacuum to give the crude product (312 mg, 78%) which was used to the next step without purification.
