Reaction Steps

A solution of methyl chloroformate (15.45 mL, 200 mmol) in CH2Cl2 (50 mL) was added to a solution of 1,2,3,4-tetrahydroisoquinoline (13.3 g, 100 mmol) and triethylamine (57 mL, 400 mmol) in CH2Cl2 (200 mL) at 0° C. The reaction mixture was stirred for 3 hours then was quenched with water. The organic layer was separated and washed with water (2×50 mL). The organic layer was then dried over anhydrous magnesium sulfate, filtered and the resultant filtrate was concentrated in vacuo to provide the title compound (19.1 g). The crude material thus obtained was used without further purification.
