Reaction Conditions

Reaction Steps

A flask was charged with 6-bromo-3-(3-methyl-isoxazol-5-yl)-4-phenyl-1H-quinolin-2-one (30 mg, 0.079 mmol)(example 39), 1 mL of THF and cooled to 0° C. A 2M solution of i-PrMgCl in THF (0.39 mL, 0.077 mmol) was added and the reaction stirred for 5 minutes at 0° C. and then cooled to −78° C. and a 2M solution of n-BuLi in hexanes (0.06 mL, 0.12 mmol) was added. After stirring for 15 minutes dimethyldisulfide (15 mg, 0.16 mmol) was added and the reaction allowed to attain RT and stirred for 30 minutes. The reaction was diluted with EtAc (10 mL) and washed with brine (2×10 mL). The organic layer was concentrated and the title product (14 mg, 50%) eluted from a 5 g SPE with 50% EtOAc/hexanes. 1H NMR (400 MHz, CD3OD) δ 7.54 (dd, 1H), 7.48 (m, 3H), 7.48 (d, 1H), 7.24 (m, 2H), 7.06 (d, 1H), 6.36 (s, 1H), 2.34 (s,3H), 2.24 (s, 3H). Mass spectrum (ESI, m/z) calcd. for C20H16N2O2S 348.1, found 349.1 (M+H).
