CLASS: ICM: C07D295-14. ICS: C07D241-04; C07D295-18. APPLICATION: JP 85-101877 13 May 1985. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) The title derivs. (I; R = CHO; R1, R2 = H, lower alkyl), useful as intermediates for drugs, were prepd. by heating I (R = H) -mineral acid salts and HCO2H at 80-130°. Thus, I (R = R1 = R2 = H).1/2H2SO4 and 80% HCO2H were heated at 115° for 2 h, H2O and HCO2H were evapd., and MeOH was added at 50°, to give, after 30 min, 88.1% I (R = CHO). 22365-47-5 and 92564-61-9 are just another two chemicals used in this study.1/2H2SO4. .
