In this scheme, bis-(6-hydroxyhexyl)malonate is first produced by reacting the Meldrum's acid and 1,6-hexanediol in the presence of a catalytic quantity of p-toluene-sulphonic acid with elimination of acetone and water. The bis-(6-hydroxyhexyl)malonate is then combined with 4-diethylaminosalicylic aldehyde in the presence of catalytic quantities of piperidine acetate to form the desired 3-(6-hydroxyhexoxycarbonyl)-7-diethylaminocoumarin.
