Versuchsvorschrift

Phenylmagnesium bromide (1.0 M in THF, 0.118 mL, 0.118 mmol) was added to a rt solution of 2-(3-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenylamino)-6,7-dihydrobenzo[d]thiazol-4(5H)-one (14 mg, 0.039 mmol) in diethyl ether (0.13 mL). The reaction was quenched with saturated ammonium chloride and extracted with EtOAc. The organic layer was concentrated in vacuo. The crude product was purified using preparatory TLC (60% acetone/hexanes) to afford 10 mg (53% yield) of the titled compound as a oil. LC-MS (M+H)+ 434.3.
