The present disclosure provides a series of compounds of the formula (I) which reduce β-amyloid peptide (β-AP) production and are useful in the treatment of Alzheimer's Disease and other conditions affected by β-amyloid peptide (β-AP) production, wherein A is a five- or six-membered heteroaromatic ring containing from one to three heteroatoms independently selected from nitrogen, oxygen, and sulfur; B is selected from phenyl and pyridinyl, D is selected from (II) E is selected from Ci-ealkyl, d-ecycloalkyl, benzyl, phenyl, and a five- to six- membered heteroaromatic ring containing one or two nitrogen atoms.

Treatment of N-substituted formamides with chlorophosphate compounds such as PhOPOCl2, EtOPOCl2, Me2NPOCl2, and (PhO)2POCl and tertiary amines such as triethylamine, pyridine, and N,N-diisopropylethylamine produced the corresponding isocyanides in high yields. This method can be used to prepare various alkyl and aryl isocyanides. isocyanide - isonitrile - formamide - dehydration - dichlorophosphate

alkyl and aryl isocyanides. Treatment of N-substituted formamides with the reagent combination of triphenylphosphine and molecular iodine, in the presence of a tertiary amine, quickly produces the corresponding isocyanides in high yields under ambient conditions. The process employs readily available and low-cost reagents, a convenient synthetic procedure, and mild reaction conditions for the synthesis
