실험 절차
To a cooled solution of 4-chloro-2-(1,1-dioxido-2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)-quinoline-6-carbaldehyde (100 mg, 0.26 mmol) in tetrahydrofuran (20 mL) was added a solution of methyl magnesium bromide in tetrahydrofuran (0.13 mL, 0.39 mmol, 3 M) at 0° C. dropwise. After being stirred for 20 minutes at the temperature below 12° C., the mixture was concentrated in vacuo. The residue was purified by preparative TLC to give 100 mg of the desired product (yield was 96%).
