Participants

Reaction Steps

To a solution of impure 1g product (0.19 g, 0.59 mmol) in a mixture of methanol and toluene (6 mL, 1:2) was added TMSCHN2 (2.0 M solution in diethyl ether) (0.6 mL, 1.2 mmol) dropwise under N2. The reaction was allowed to warm to rt and stirred for 2 h. The reaction mixture was concentrated and purified by flash column chromatography eluting with a linear gradient ranging from 0 to 50% EtOAc-hexanes to provide 0.15 g (75%) of product 34 as an off white solid. 1H NMR (300 MHz, CDCl3) δ 3.93 (s, 3H), 6.88-6.95 (m, 1H), 7.06-7.16 (m, 5H), 7.45-750 (m, 1H), 9.22 (s, 1H). LC-MS (CI): m/z 336.0 [(M+H)+ C16H11ClFNO2S requires 335.02].
