3-Amino-4-chloropyridine → Benzamide,n-(4-chloro-3-pyridinyl)-3-(cyclopentyloxy)-4-methoxy-

Participants

Reaction Steps

A stirred solution of 4-chloropyrid-3-ylamine (1.94 g) and 3-cyclopentyloxy-4-methoxybenzoyl chloride (3.85 g) in pyridine (50 mL) is heated at 80° C. for 7 hours and then it is allowed to stand overnight. The reaction mixture is evaporated, to give a brown oil, which is subjected to mplc on silica gel, using diethyl ether as eluent, to give N-(4-chloropyrid-3-yl)-3-cyclopentyloxy-4-methoxybenzamide (3.1 g), m.p. 130-132° C.
