7-(3-chloropropoxy)-3-(hydroxymethyl)chromen-4-one → Abaperidone

Participants

Reaction Steps

By the procedure described above, starting from 2.0 g (7.5 mmoles) of 7-(3-chloropropoxy)-3-(hydroxymethyl)chromen-4-one and 1.93 g (7.5 mmoles) of 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole hydrochloride, a solid was obtained by crystallization of the crude product from dimethylformamide to yield 1.27 g of 7-[3-[4-(6-fluoro-1,2-benzisoxazole-3-yl)piperidin-1-yl]propoxy]-3-(hydroxymethyl)-chromen-4-one, mp 200°-202° C.
