Steps:

Preparation of CH₃NH₃I
In a 500 mL round bottom flask, a methanol solution of methylamine (60.4 mL, 40%, 592mmol; Wako Pure Chemical Industries, Ltd.) was added dropwise over 10 min to an aqueous solution of HI (65.0 mL, 57 wt%, 492 mmol; Wako Pure Chemical Industries Ltd., Japan) at 0 °C, and stirried for 2 h. The resulting white solids were collected by filtration, and dried in vacuo for 24 h at 60 °C. The obtained crude CH3NH3I was purified by recrystallization from a slow diffusion of dry diethyl ether (dehydrated, Kanto Chemical Co. Ltd., Japan, further purified with Glass contour) into a dry methanol (super dehydrated, Wako Pure Chemical Industries Ltd., Japan) solution of CH3NH3I. The resulting CH3NH3I (75.6 g, 476 mmol, 97%yield) was isolated by filtration in an inert glovebox under N2 as colorless crystalline platelets.
