Reaction Steps
7.5M Sodium hydroxide solution (0.983 ml, 7.37 mmol) was added to a solution of (E)-methyl 3-(4-((1R,3R)-2-(2-fluoro-2-methylpropyl)-3-methyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indol-1-yl)phenyl)acrylate (310 mg, 0.74 mmol) in methanol (5 ml). The mixture was stirred at 20° C. for 2 hours. The reaction mixture was purified by ion exchange chromatography, using an SCX-2 column. Fractions containing the desired product were eluted from the column using 7M NH3/methanol and pure fractions were evaporated to dryness to afford a yellow solid. The crude product was purified by preparative HPLC (Waters SunFire column, 5μ silica, 50 mm diameter, 100 mm length), using decreasingly polar mixtures of water (containing 0.1% formic acid) and MeCN as eluents. Fractions containing the desired compound were evaporated to dryness and then loaded onto SCX-2 column and eluted with 7N ammonia in methanol to afford the title product (63.0 mg, 21.02%) as a yellow solid. 1H NMR (400 MHz, DMSO, 30° C.) δ 1.06 (3H, d), 1.30 (3H, d), 1.47 (3H, d), 2.53-2.64 (2H, m), 2.79 (2H, s), 3.10 (1H, d), 5.08 (1H, s), 6.47 (1H, d), 6.98 (1H, t), 7.06 (1H, t), 7.19-7.37 (3H, m), 7.44 (1H, d), 7.56 (1H, d), 7.63 (2H, d), 10.81 (1H, s), 12.30 (1H, s). m/z: ES+ [M+H]+ 407.
