Condensation of 2,2-bis(hydroxymethyl)propionic acid (VIII) with morpholine (IX) in the presence of DCC and HOBt gave amide (X). The cyclic ketal (XI) was then obtained by acid-catalyzed condensation of imidazole aldehyde (VII) with diol (X) using azeotropic removal of water. Oxidation of the sulfide group of (XI) with meta-chloroperbenzoic acid furnished sulfone (XII). The methylsulfonyl group of (XII) was finally displaced with cyclopropylamine (XIII) to provide the title compound
