실험 절차

tert-butyl(4-(hydroxymethyl)pyridin-2-yl)carbamate (600 mg, 2.679 mmol) was first treated with SOCl2 (3 ml) in CH2Cl2 (5 ml) at rt for 2 hrs. The solvent was removed to get a crude tert-butyl(4-(chloromethyl)pyridin-2-yl)carbamate. Then following General Procedure A, the title compound (667 mg, 68%) was prepared from 2-amino-4-chlorobenzenethiol (641 mg, 4.019 mmol), K2CO3 (1.8 g, 13.39 mmol) in DMF (20 ml).
