YieldReaction ConditionsOperation in experiment
55% Sodium acetate (72 mg, 0.88 mmol) was added to a mixture of tert-butyl 2,7- diazaspiro[4.4]nonane-2-carboxylate (CAS: 236406-49-8; 80 mg, 0.3 mmol; HC1 salt), lH-<strong>[3314-30-5]benzimidazole-2-carboxaldehyde</strong> (59 mg, 0.36 mmol) in MeOH (10 mL) sodium acetate (72 mg, 0.88 mmol) at 0°C. After, the reaction was stirred for 30 min at rt, followed by the mixture reaction was cooled to 0°C, and acetic acid (18.2 mg, 0.3 mmol) and sodium cyanoborohydride (22 mg, 0.35 mmol) were added. The mixture was stirred rt overnight. Then additional acetic acid (2eq), lH-benzimidazole-2- carboxaldehyde (leq) and sodium cyanoborohydride (1.5eq) were added at 0°C and the mixture was stirred at rt overnight. Water was added and the mixture was extracted with EtOAc (3 x 20 mL). Then, the organic phase was separated, dried over MgS04, filtered and concentrated in vacuo. The crude material was purified by flash chromatography (silica, gradient from MeOH/ DCM(9:1) to DCM 0/100 to 100/0). The desired fractions were collected and concentrated in vacuo to yield intermediate 27 (60 mg, 55 percent yield) as a yellow oil.
