Potassium Carbonate → Methyl 3-[2-cyclopropylmethoxy-3'-(3-heptyl-1-methylureido)biphenyl-4-yl]propanoate

Participants

Reaction Steps

In a manner similar to that of Example (25a), by reaction of 170 μL (1.75 mmol, 1.5 eq) of methylcyclopropyl bromide and 500 mg (1.17 mmol, 1 eq) of methyl 3-[3′-(3-heptyl-1-methylureido)-2-hydroxybiphenyl-4-yl]propanoate (prepared in Example 15f) in 10 ml of methyl ethyl ketone in the presence of 500 mg (3.61 mmol, 3 eq) of potassium carbonate, methyl 3-[2-cyclopropylmethoxy-3′-(3-heptyl-1-methylureido)biphenyl-4-yl]propanoate is obtained in oil form and is used in the following reaction without further purification.
