Reaction Steps

A solution of 2,6-dimethylcyclohexyl 3,4-bis(benzyloxy)-5-(dimethylcarbamoyl)-1-(4-methoxyphenyl)-1H-pyrrole-2-carboxylate (45) (73 mg, 0.12 mmol) in MeOH (6 mL) was passed through a Thales ‘H-cube’ cartridge (10% Pd/C) at a flow rate of 1 mL/min at 26° C. under H2 (full H2 mode). The output was concentrated in vacuo and the crude product was purified by preparative HPLC (Waters, Acidic (0.1% formic acid), Waters X-Select Prep-C18, 5 μm, 19×50 mm column, 5-95% MeCN in Water) to afford 2,6-dimethylcyclohexyl 5-(dimethylcarbamoyl)-3,4-dihydroxy-1-(4-methoxyphenyl)-1H-pyrrole-2-carboxylate (UL1-113) (15 mg, 29%) as a yellow solid: m/z 431 (M+H)+ (ES+); 429 (M−H)− (ES−). 1H NMR (400 MHz, DMSO-d6) δ: 8.67-8.40 (m, 2H), 7.15-7.05 (m, 2H), 6.91-6.85 (m, 2H), 5.05 (br s, 1H), 3.76-3.75 (m, 3H), 2.82 (br s, 6H), 1.64-0.94 (m, 6H), 0.74-0.57 (m, 6H), 0.57-0.40 (m, 2H).
