Procedure

A mixture of 14 parts of 6-chloro-3,4-dihydro-3-(2-hydroxyethyl)-4-phenyl-2(1H)-quinazolinone, 5 parts of sodium acetate and 200 parts of methanol is hydrogenated at normal pressure and at room temperature with 2 parts of palladium-on-charcoal catalyst 10%. After the calculated amount of hydrogen is taken up, the catalyst is filtered off and the filtrate is evaporated. The residue is stirred in 2,2'-oxybispropane. The solid product is filtered off and stirred in 200 parts of water. It is filtered off again and dried, yielding 11.2 parts (91%) of 3,4-dihydro-3-(2-hydroxyethyl)-4-phenyl-2(1H)-quinazolinone; mp. 141° C.
