実験手順

Sodium hydride (2.2 mg, 0.055 mmol, 60% by weight dispersion in oil) was slowly added to a stirred solution of 5′(1-(benzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido)-N,N,2′-trimethylbiphenyl-4-carboxamide (21 mg, 0.048 mmol) in a mixture of 0.90 mL of anhydrous tetrahydrofuran (THF) and 0.10 mL of anhydrous N,N-dimethylformamide (DMF). The resulting suspension was allowed to stir for 3 minutes before iodomethane (0.0048 mL, 0.072 mmol) was added to the reaction mixture. An additional aliquot of sodium hydride and iodomethane were required to consume all of the starting material which was monitored by LCMS. The crude reaction product was evaporated to dryness, redissolved in a minimum of DMF and purified by preparative LCMS chromatography to yield 5′-(1-(benzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido)-2′-(isopropoxymethyl)-N,N-dimethylbiphenyl-4-carboxamide (9.1 mg, 42%) ESI-MS m/z calc. 456.2, found 457.5 (M+1)+. Retention time of 2.94 minutes. 1H-NMR (400 MHz, CD3CN) δ 0.91-0.93 (m, 2H), 1.41-1.45 (m, 2H), 2.23 (s, 3H), 3.00 (s, 3H), 3.07 (s, 3H), 3.20 (s, 3H), 5.81 (s, 2H), 6.29-6.36 (m, 2H), 6.56 (d, J=8.0 Hz, 1H), 6.69 (s, 1H), 6.92 (dd, J=1.6, 7.9 Hz, 1H), 7.17 (d, J=8.1 Hz, 1H), 7.28 (d, J=8.1 Hz, 2H), 7.46 (dd, J=1.8, 6.4 Hz, 2H).
