Dimethylformamide → HCID 136375556, compound

Participants

Reaction Steps

100 mg of the product of Step D of Example 1 were introduced into 4 ml of dimethylformamide, 108 mg of potassium carbonate and 106 mg of [4-(methoxycarbonyl)-benzyl]-bromide. The mixture was stirred at ambient temperature for 6 hours, followed by pouring into water, extracting 3 times with ethyl acetate, washing with a saturated solution of sodium chloride and evaporating to dryness under reduced pressure. After chromatography on silica (eluant: methylene chloride-ethyl acetate: 6-4), 55 mg of the expected product melting at 170° C. were obtained.
