Source of material
A solution of 1-iodonaphthalen-2-ol (1.0 mmol), 4-oxo-4H-chromene-3-carbaldehyde (1.0 mmol) and tert-butyl isocyanide (1.0 mmol) in DMF (2.0 mL) was heated under microwave irradiation at 150 °C for 20 min. After the microwave vial was cooled to room temperature, the solvent was removed and the residue was purified by silica gel column chromatography using a gradient of ethyl acetate/hexane (0–100%) to afford the targeted product (Z)-3-((tert-butylamino)methylene)-2-(2-hydroxynaphthalen-1-yl)chroman-4-one. The product was dissolved in methanol and crystals of the title compound were obtained by slow evaporation within seven days (Tables 1 and 2).

Comment
Chromene derivatives, as an important class of heterocycles, are used for various applications [4], [5], [6], [7]. The chromene derivatives show various pharmacological properties [8], [9], [10], [11]. Recently, for their pharmacological and biological applications, the synthesis of chromene derivatives has drawn more attention [12, 13]. In this work, we report the synthesis of the title compound using a three-component reaction with assistance of microwave irradiation in high yield.
The asymmetric unit consists of a chromone core and a naphthyl moiety. It is clear to find that the double bond of chromone is transferred from the inner to the outer, which leads the bond angles of C6–O2–C9 is 112.91(15)° and C8–C9–O2 is 109.99(15)°, respectively. And the double bond length of C8–C10 is 1.386(3) Å. The main chromene plane and the second naphthol plane are almost vertical to each other. In addition, the amino group does not rotate freely and is almost coplanar with chromone unit. The reason is that the amino group forms an intramolecular N1–H1···O1 hydrogen bond with the carbonyl group and N1–H1 and O1–H1 bond lengths are 0.860 and 1.968 Å, respectively. The N1···O1 separation is 2.645(3) Å. The bond angle of C8–C10–N1 is 124.3(2)°. For this crystal, all bond distances and angles are consistent with the expectation and in accord with the reported in the references [14, 15].
