3-[4-chloro-2-fluoro-5-(phenylmethoxy)-phenyl]-6-(dimethylamino)-1-methyl-1,3,5-triazine-2,4(1H,3H)-dione → 3-[4-chloro-2-fluoro-5-(hydroxy)phenyl]-6-(dimethylamino)-1-methyl-1,3,5-triazine-2,4(1H,3H)-dione

Participants

Reaction Steps

A mixture of 4.62 g (11.4 mmol) of 3-[4-chloro-2-fluoro-5-(phenylmethoxy)phenyl]-6-(dimethylamino)-1-methyl-1,3,5-triazine-2,4(1H,3H)-dione and 460 mg of 10% palladium on charcoal in 50 mL of ethyl acetate was placed in a Paar bottle and was agitated under 45 psi hydrogen over a 14 hour period. It was filtered and washed with ethyl acetate. The filtrate was concentrated in vacuo and the resultant crude product flash chromatographed over silica gel eluting with a 1:1 v:v mixture of ethyl acetate and hexane to give 3.2 g of the title compound as a pale grey solid, m.p.: 247°-249° C. (dec); 1 -NMR (DMSO-d6) ppm 7.45 (d, 1H), 6.95 (d, 1H), 3.3 (s, 3H), 3.0 (s, 6H).
