11.2.1 Step 1.5-(4-Hydroxyphenyl)-1-methyl-1H-imidazole-2-carbaldehyde (F63-1)
To a solution of 5-bromo-1-methyl-1H-imidazole-2-carbaldehyde (500 mg, 2.65 mmol), (4-hydroxyphenyl)boronic acid (547 mg, 3.97 mmol) and tetrakis(triphenylphosphine) palladium(0) (153 mg, 0.132 mmol) in DMF (7 mL) was added Na2CO3(1 M, 5.29 mL). The resulting mixture was purged with nitrogen gas before being irradiated in the microwave at 130 °C for 10 min. The reaction mixture was then poured into water and pH was adjusted to pH 6 with acetic acid. The reaction mixture was extracted with EtOAc twice. The combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo. The resulting solid was triturated with a small amount of EtOAc to provide F63-1 as an orange solid (425 mg, 79%). Analytical method 5; tR= 0.47 min; [M+H]+= 203.1. |

Na2CO3 (30 mL, 30.0 mmol) was stirred for 5 h at 90° C. under an N2-atmosphere. The mixture was filtered through HyFlo and the filtrate was partitioned between EtOAc (100 mL) and H2O (50 mL). The aqueous phase was extracted with EtOAc (3*50 mL). The combined organic phases were washed with brine (20 mL), dried over Na2SO4, filtered, and concentrated to dryness in vacuo to afford E3-1 (assumed to be 10 mmol) as an olive-colored solid. |

To a solution of 5-bromo-1-methyl-1H-imidazole-2-carbaldehyde (2 g, 10.58 mmol) in MeOH (30 mL) cooled in an ice bath, was added sodium borohydride (0.801 g, 21.16 mmol) in several portions. The resulting mixture was stirred in an ice bath for 60 min and then quenched with water and MeOH at 0° C. and concentrated in vacuo to dryness.

EtMgBr (1 M in THF, 2.08 mL, 2.08 mmol) was added dropwise over 1 minute to a solution of 5-bromo-1-methyl-1H-imidazole-2-carbaldehyde (375 mg, 1.984 mmol) in THF (9.9 mL) in a round bottom flask charged with a magnetic stir bar under an atmosphere of N2at 0 °C. The resulting mixture was allowed to warm to rt and stirred overnight. The reaction mixture was then diluted with sat. NH4Cl (25 mL), DCM (100 mL), and H2O (25 mL). The organic phase was separated, and the aqueous layer was washed with DCM (2 x 50 mL). The combined organic phases were dried with Na2SO4, filtered, and concentrated in vacuo to provide a crude yellow oil. The crude oil was purified by silica gel flash chromatography (24 g column, liquid loading (in DCM), eluting with 0-5% MeOH:DCM), but the product-containing fractions contained significant impurities. The fractions were concentrated in vacuo, and the resulting oil was repurified via silica gel flash chromatography (24 g column, liquid loading (in DCM), eluting with 0-50-100% EtOAc:heptane) to provide F68-1 (105 mg, 24% yield) as a colorless oil.
