実験手順

To a solution of 4-(1-(4-cyclobutyl-2-methyl-5-(4,5,6,7-tetrahydro-3H-imidazo[4,5-c]pyridin-2-yl)benzoyl)piperidin-4-yl)benzonitrile (406.3, 190 mg, 0.30 mmol, 1.00 equiv, 75%) in tetrahydrofuran (10 mL) were added NaBH(OAc)3 (252 mg, 1.13 mmol, 3.00 equiv, 95%) and HCHO (37%) (2.2 mL, 2.00 equiv). The resulting mixture was stiffed for 2 h at 40° C. in an oil bath and then concentrated under reduced pressure. The residue was diluted with dichloromethane and washed with aqueous saturated sodium bicarbonate and brine. The organic layer was dried (Na2SO4) and concentrated. The crude product (˜80 mg) was purified by Prep-HPLC with the following conditions (1#-Pre-HPLC-001(SHIMADZU)): Column, Xbridge Prep C18, 5 um, 19*150 mm; mobile phase, water with 0.03% NH3H2O and CH3CN (36% CH3CN up to 48% in 8 min, up to 100% in 1 min, down to 36% in 1.5 min); Detector, Waters 2489 254&220 nm. The fractions containing pure compound were combined and lyophilized to yield 23.4 mg (16%) of the title compound as a white solid. m/z (ES+) 494 (M+H)+. 1H NMR (300 MHz, CD3OD): δ 7.69 (d, J=6.0 Hz, 2H), 7.48 (d, J=6.0 Hz, 2H), 7.37-7.31 (m, 1H), 7.26 & 7.15 (2 singlets, amide rotamers, Ar—H, 1H), ˜4.9 (1H partially obscured by water peak), 4.02-3.90 (m, 1H), 3.73-3.57 (m, 1H), 3.57 (s, 2H), 3.34-3.21 (m, 1H), 3.06-2.94 (m, 2H), 2.90-2.77 (m, 4H), 2.54 (s, 3H), 2.45 & 2.34 (2 singlets, amide rotamers, ArCH3, 3H), 2.11-1.86 (m, 6H), 1.86-1.54 (m, 4H).
