Formamide dimethylacetal

The formamidine is prepared by heating the primary amine in DMF-dimethylacetal (81-100% yield). Deprotection is effected by heating in EtOH with ZnCl2. LiAlFLi (Et20, reflux), hydrazine (AcOH, MeOH), KOH (MeOH, reflux),dilute ammonia (high yield) and coned. HCl (reflux, 65-90% yield) are also known to cleave the formamidine group. Treatment of the formamidine in MeOH/H20 with or without TEA results in the formation of a formamide (48-100% yield). ... [Pg.830]
