Reaction Steps

To a suspension of 3-benzo[d]furan-2-yl-1-perhydro-2H-pyran-2-yl-1H-indazole-5-carbonitrile (167 mg, 0.49 mmol) and N-amino-2-(dimethylamino)acetamide (171 mg, 1.46 mmol) in anhydrous methanol (1.0 mL) in a screw-top pressure tube was added sodium methoxide (445 μL of a 25% w/w in methanol). The tube was sealed and heated in a 100° C. oil bath for 21 h. An additional amount of N-amino-2-(dimethylamino) acetamide (171 mg, 1.46 mmol) was added and the reaction heated for an additional 2 days. The reaction was cooled, evaporated to dryness and partitioned between ethyl acetate and satd. ammonium chloride. The organic layer was separated, washed with brine, dried over MgSO4 and concentrated in vacuo to give a yellow solid. Purification of the residue by flash chromatography on silica gel using 5% methanol in dichloromethane then 20% methanol in dichloromethane gave the desired product (15 mg, 7% yield) as a pale yellow foam. ES-MS (m/z) 443 [M+H]+.
