The downstream synthesis method of this compound is introduced below.
To a solution of N-(2-(difluoromethoxy)-6-methylpyridin-3-yl)-3-(2-isopropylphenyl)azetidine-3-carbox-amide Ex 3 (68 mg, 0.18 mmol) and 3-hydroxy-2,2-dimethyl-propanal (25 mg, 0.245 mmol) in MeOH (2 mL) under inert atmosphere is added sodium cyanoborohydride (18 mg, 0.29 mmol). The reaction mixture is stirred at 50C for 2 h (reaction monitored by LCMS) and is then quenched with water (2 mL). The mixture is diluted with MeCN (2 mL) and is then purified by prep. HPLC (Prep-HPLC-3 conditions) to give the title compound Ex 11-17 (46 mg, 55% yield) as a colorless glass. LCMS-1 : tR = 0.79 min, [M+1]+ 462.41; 1H NMR (500 MHz, CDC )<5: 8.61 (d, J = 8.1 Hz, 1 H), 8.07 (s, 1 H), 7.42-7.35 (m, 3 H), 7.33-7.29 (m, 1 H), 7.19 (d, J = 7.7 Hz, 1 H), 6.92 (d, J = 8.1 Hz, 1 H), 4.25 (s br, 2 H), 3.70 (s br, 2 H), 3.50 (s, 2 H), 2.60 (s, 2 H), 2.53-2.45 (m, 1 H), 2.39 (s, 3 H), 1.14 (d, J = 6.7 Hz, 6 H), 0.94 (s, 6 H).
