실험 절차

To a flask containing ice cold suspension of N-(4-methoxybenzyl)thiazol-4-amine (Intermediate PPPPP; 0.085 g, 0.384 mmol) in THF (1.408 ml) was added lithium bis(trimethylsilyl)amide (0.403 ml, 0.403 mmol) drop wise over 10 min. The mixture was stirred for 15 minutes prior to the addition of a solution of perfluorophenyl-1-chloroisoquinoline-6-sulfonate (From Step 1 in Example 73; 0.15 g, 0.366 mmol) in THF (1.0 ml). After 45 minutes of stirring (ice melt) LCMS indicated that the reaction was nearly complete. The mixture was allowed to stir and slowly warm to room temperature overnight. LCMS indicated that the reaction was complete. The reaction was quenched by the addition of acetic acid (˜2 ml) and the resulting mixture was dried under reduced pressure and purified via silica gel chromatography (40 g silicycle HP column) ramping EtOAc in heptane (0-50%) providing product 1-chloro-N-(4-methoxybenzyl)-N-(thiazol-4-yl)isoquinoline-6-sulfonamide. m/z (ESI) 446.1 (M+H)+.
