Procedure: Place 5-(4-formyl-2-methoxyphenoxy)pyrazine-2-carboxamide (Example 719, Part A) (0.700 g, 2.56 mmol), 2-isopropoxyethylamine (0.278 g, 2.69 mmol) and 3 Å molecular sieves in a vial. Add methanol (12.8 mL), cap and stir overnight. Add NaBH4 (0.0969 g, 2.56 mmol) and stir until the gasses stop evolving. Load the reaction mixture directly onto a 25 g ISCO® pre-load column. Dry the column in a vacuum oven at room temperature. Purify by eluting through a 40 g ISCO® column with 5% to 20% (2.0 M NH3 in methanol) in ethyl acetate over 45 minutes. Concentrate the fraction containing the product, then take it up in EtOAc (100 mL). Wash the organic solution with 1.0 N NaOH (2× 25 mL), dry it over Na2SO4 filter and concentrate to give the title compound (0.512 g, 55.5%): TOF MS ES+ 361.2 (M+H)+, HRMS calcd for C18H25N4O4 361.1876 (M+H)+, found 361.1891, time 0.38 min; HPLC [YMC-Pro pack C-18 (150×4.6 mm, S-5 microm), 0.05% TFA/acetonitrile in 0.05% TFA/water at 1.0 mL/min, 10-20% over 5 min, 20-95% over 18], tR=9.4 min, 100% purity.
