In a related procedure, protection of methyl (R)-lactate (XXIV) as the corresponding tetrahydropyranyl ether, followed by treatment with morpholine, gave amide (XXV). Subsequent addition of 2,4-difluorophenylmagnesium bromide (XXVI) to (XXV) afforded propiophenone (XXVII), which was converted into epoxide (XXVIII) by reaction with the ylide resulting from trimethylsulfoxonium iodide. Epoxide ring opening with 1,2,4-triazole (XVI) produced the triazolyl alcohol (XXIX). After acid cleavage of the tetrahydropyranyl protecting group of (XXIX), recrystallization of the diastereomeric mixture provided diol (XXX). Mesylation of the secondary hydroxyl group of (XXX), followed by basic cyclization of the resulting hydroxy mesylate (XXXI), produced epoxide (XXXII). Epoxide (XXXII) was reacted with 2,2-diethoxyethylamine (X) in the presence of Ti(iPrO)4 to give the amino alcohol (XXXIII). Condensation of amine (XXXIII) with carbamate (IX) generated urea (XXXIV), which was then cyclized to imidazolone (XVII) in the presence of HCl. This was finally converted to the title imidazolidinone by catalytic hydrogenation as above.
