5,5-Diphenylbarbituric acid → HCID 22055301, compound

Participants

Reaction Steps

To the aqueous phase was added hydrochloric acid (32%, 0.32 L), while keeping the temperature below 20° C. The methanol was then distilled out of the mixture at reduced pressure, and the resulting precipitate was filtered and dried to provide a crude product (0.366 kg) containing 1-methoxymethyl-5,5-diphenylbarbituric acid (78% w/w), 5,5-diphenylbarbituric acid (6% w/w), and 1,3-bis(methoxymethyl)-5,5-diphenylbarbituric acid (2.7% w/w).
