carbamate-protected guanidines with various alkyl halides and mesylates is described. This protocol proceeds via deprotonation of the acidic N-carbamate hydrogen of the guanidine under biphasic conditions using a catalytic amount of a tetrabutylammonium salt as a phase-transfer catalyst. In this manner, highly functionalizedguanidines can be obtained. The reaction is tolerant of a wide range of functional groups
