Reaction Steps

Thionyl chloride (1.629, 13.6 mmol) was added dropwise to a solution of (3S)-7-hydroxy-1,2,3,4-tetrahydro-3-isoquinolinecarboxylic acid (0.75 g, 3.9 mmol) in methanol (30 mL) at about 0° C. under N2. The solution was warmed to about 25° C. and stirred for about 6 h, then was concentrated. The residue was washed with ether, followed by 1:1 ether pentane and dried under vacuum to yield 0.85 g of product as a white solid (89% yield). 1H NMR (d6DMSO) δ 3.09 (m, 2H); 3.78 (s, 3H); 4.23 (apparent s, 2H); 4.51 (m, 1H); 6.61 (s, 1H); 6.72 (d, J=3 Hz, 1H); 7.04 (d, J=3 Hz, 1H).
